Failed because #19.

I'm not very familiar with Travis yet. Is it possible to specify just DMD and LDC as compilers, rather than specific versions? With this change, I have to remember to update travis.yml every time a new compiler version is released, if I want to test the code with the latest version.

I have tried to write - dmd but it seems there is an bug in Travis-CI:

The command "curl  > ~/dmd.zip" failed and exited with 2 during .

If you forget to update .travis.yml then travis will use old version of compiler.
In 99% cases if Travis success with old version then it will success with newer one.

[MartinNowak]

For now only compilers with specific versions are supported (e.g. dmd-2.066.1). This will remain the case until there is a generic way to obtain the latest version of each compiler. The default compiler is dmd-2.066.1. It's often a good idea to maunally update the compiler version, so that you can handle deprecations and such.

[MartinNowak]

Why do you need to test OSX. That wouldn't work with apt-get anyhow.

[9il]

When (if) Travis will support OS X apt-get raise an error like reminder.

[kyllingstad]

Yes, but that error will be completely unrelated to the pull request that triggers it, and that is unfortunate. If Travis does not support D on OS X, the os: section should just be removed.

[9il]

Removed

[MartinNowak]

It already does support D on OSX, but there isn't anything platform specific in this library, so you shouldn't needlessly waste Travis' resources.

[kyllingstad]

Ok, I'll merge this as soon as the LDC issue is sorted out and the build succeeds. Thanks!
