Theoretically, a colon is only necessary in things like

if yes: print "yes"

Since otherwise the parser can figure out when to stick a colon. However,
usability studies show people are more comfortable when the beginning of a
block is signaled, and I can see why:

if yes
	print "yes"

Seems....naked. Much less readable then 

if yes:
	print "yes"

Guido didn't want 10 ways (or even 2) to spell things, so the colon is
mandated for all.
