Change "pred" to "pure fn" in all libraries and test cases 2011-08-23 18:25:50 -07:00			`pure fn even(x: uint) -> bool {`
Reformat for new syntax 2011-07-27 14:19:39 +02:00			`if x < 2u {`
			`ret false;`
Reformat This changes the indexing syntax from .() to [], the vector syntax from ~[] to [] and the extension syntax from #fmt() to #fmt[] 2011-08-19 15:16:48 -07:00			`} else if x == 2u { ret true; } else { ret even(x - 2u); }`
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 11:56:34 -07:00			`}`
