in thread mini-golf: convert integer into list of powers of two

That's 32 by my reckoning...

Using the assign-within-grep trick I applied to BrowserUK's solution, it is possible to take it down to 31 though:

0        1         2         3
1234567890123456789012345678901
sub{grep$_[0]&($_=1<<$_),0..31}
