… bit of old commented out code relating to the equivalent change for access some time ago.

Moreover,
- use of IS_POS_INTOBJ in multiple places for readability
  and efficiency
- enforce consistent behavior for ELM/ASS/ISB/UNB, and also between
  interpreted and compiled code: positive integers as before, while
  anything else (including non-positive integers) is sent through
  method dispatch
- some code cleanup (indention, uniform whitespace in comments, etc.)

…lti-index

This provides parser interpreter and coder support for multi-index access to lists
At the moment all such accesses are translated into calls to ELM_LIST with a single
argument which is a plain list of the indices, but there is kernel support for
a fast-path for two arguments later if one is needed.

At this stage printing of coded expressions, assignment, IsBound and Unbind are all
to do, as are nested list accesses. l[...][x,y].

This reverts commit 3b00d9f.

This is obsoleted by GapDOC.

Alexander moved this to the gap-distribution repository

etc/install-tools.sh is a script to unpack etc/tools.tar.gz archive included in the GAP distribution and described in etc/README.tools.

Added:
- IsNonAtomicComponentObjectRep
- IsReadOnlyPositionalObjectRep
- IsAtomicPositionalObjectRep
- FixedAtomicList
- MakeWriteOnceAtomic

… reduce output size

Example of old behaviour:

gap> f := function()
>  S := [];
>  return S[0];
> end;
gap> f();
Error, no 1st choice method found for `[]' on 2 arguments called from
<compiled or corrupted statement>

Now correctly identifies 'S[0]' as the incorrect code.

Fix a lot of instances in lib/thread1.g where arg is used without

The previous behaviour was to call ShallowCopy which resulted in
an infinite loop, as reported by Stefan Kohl.

The new release of Semigroups triggered a harmless diff because of changing the point at which semigroup learned that it has a multiplicative zero.

place a warning instead of an error and added a warning (for now) when the new
syntax is used, to help debug accidental uses.

Also added SyntaxWarning as a proper function.

They now include the temporary warning.

Not sure this is ever performance critical, but having the function in the kernel
is useful in HPCGAP and it seems like an odd ommission.

This test should check that it is possible to build all three main GAP manuals.

cover both prime and non-prime cases, and matrices

Previously, we stored the modulus in three places:
1. in the type object, accessed via DataType( TypeObj( x ) ),
2. in family object, accessed as fam!.modulus,
3. in family object, accessed as  Characteristic(fam).

To retrieve the modulus for a ZmodnZObj, one can moreover also use
ModulusOfZmodnZObj(x) or Characteristic(x).

This patch changes the code to consistently use Characteristic(fam),
and gets rid of fam!.modulus. The DataType is not use anymore, but is
retained for now, as at least the Browse package is using it. Once
that is changed, we can also get rid of the corresponding three
SetDataType calls in ffee.gi and zmodnz.gi.

This is a bit of a hack, but improves performance a bit
