WARNING: change in syntax for for in upcoming release: 6.3.x

[lmorg]

The for builtin is switching from parenthesises to curly braces:

old syntax: ( ... ; ... ; ... )
new syntax: { ... ; ... ; ... }

This is due to the deprecation of = and let, and how for acted as a proxy for these builtins.

The updated manual can be found at https://dev.murex.rocks/commands/for.html

This change is already in develop and will be pushed to master as part of the 6.3.x release.
