The 0.1.4 source tarball of Nemerle compiler has hit our server. This is yet another incremental release before 0.2.0.

There's a source tarball as well as MSI, DEB and RPM packages.

The language

• The assignment operator <- has been changed to =. This was a long discussed issue. <- is still available, it will be deprecated in 0.2.0, and removed later. Please convert your sources, under Unix: perl -p -i -e 's/<-/=/g' *.n should do the trick.
• The ; is now optional after } in expressions. That is both: while (cond) { ... }; foo () and while (cond) { ... } foo () are correct.
• Expressions starting with keywords have now much lower priority. In particular: foo += fun (_) {...}; needs to be now written like this: foo += (fun (_) {...}); Sorry. This is however to be reconsidered.
• 1_000_000 is now proper literal (like in Ada or Perl).
• ref and out parameters are supported now.
• try {...} catch {...} finally {...} is now proper code, try { f () } catch {...} is too, but try f () catch {...} is not.

The library

• Tuple and list types now provide proper ToString(), Equals() and GetHashCode() methods.
• List.Sort() was sorting in the opposite direction, we fixed that. Please update your sources.

The compiler

• Some fixes to attribute support, in particular attribute classes can be defined and used in the same compilation.
• Several new checks (like requiring implemented interface methods to be public etc).
• Several bugfixes.

Other stuff

• Added examples written by students during Nemerle course. Some new OpenGL/SDL examples by Kamil.

Have fun testing it :-)
