Wow!  Completely out-classed :-)

I did try this one in my efforts:

main="\360\017\307\310";

which compiles, but obviously doesn't work.

So... I see the light now: you can write var=5; and it'll assume int,
and so if you do main=5; it will create asm label _main against a
memory location initialised to that constant ... due to lack of type
checking, that'll make the linker happy and voila.  Excellent.
