Implement default function arguments (for Python functions). TODO: Decide if we really need separate bytecode for creating functions with default arguments - we would need same for closures, then there're keywords arguments too. Having all combinations is a small exponential explosion, likely we need just 2 cases - simplest (no defaults, no kw), and full - defaults & kw. 2014-02-01 08:05:04 -05:00			`def fun1(val=5):`
			`print(5)`

			`fun1()`
			`fun1(10)`

			`def fun2(p1, p2=100, p3="foo"):`
			`print(p1, p2, p3)`

			`fun2(1)`
			`fun2(1, None)`
			`fun2(0, "bar", 200)`

tests: Make tests pass on pyboard. 2014-04-13 12:46:30 -04:00
