[Technology] Vala features

Here are a few nifty vala features I did not already know.



I can run "vala foo.vala" and it apparently does "valac foo.vala; ./foo".



Also, I can have preprocessing directorives like this



"#ifdef DUCK

stdout.printf ("QUACK");

#else

stdout.printf ("Woof");

#endif"



I can't seem to use #define, but I can do

"valac -D DUCK foo.vala"

which will define the symbol.



Hooray/boo for conditional compilation!
