You can use Lua, commonly used to script games.
There are some implementations in JavaScript, for example:
which is optimized and fast.
It might have the same issue with longs, thought, like most languages compiling to
JavaScript... unless a specific workaround / implementation is made.

I haven't tried it in GWT...
