Bring back if-check Add "if check" (expr_if_check), a variation on check that executes an "else" clause rather than failing if the check doesn't hold. 2011-06-16 13:56:34 -05:00			`// error-pattern:Number is odd`
Change "pred" to "pure fn" in all libraries and test cases 2011-08-23 20:25:50 -05:00			`pure fn even(x: uint) -> bool {`
Reformat for new syntax 2011-07-27 07:19:39 -05:00			`if x < 2u {`
Convert ret to return 2012-08-01 19:30:05 -05:00			`return false;`
