Anyone coming from ruby would feel right at home, but i'm having trouble
finding precedent in any other language for that behavior. You may be right.

Ideally, a tab character would be a syntax error in Swift, period. Eat it,

​I don't think it's the language's job to enforce preferences here,
especially given that holy wars have been fought over indentation (as well
as things much less important). Having 3 lines all started by the same
number of tabs, but with two having spaces as well for sub-tab-length
indentation, should never be an error.
