+1 ^
+1 too:
'f(x++)' what's the value of x after executing this function call?
If f is a function with a normal argument, the new value is x +
1, if f is a function with a lazy argument, the new value can be
anything (depends on how many time the expression is evaluated).
So the lazy keyword hurts maintainability: you need an IDE which
color differently the callsite to be usable, really ugly..
How about improving 'f({ return x ++ })' to either f({^x++})' (^
is return in Smalltalk) or 'f({x++})'?
