ATM "func"/[args] notation has one big advantage: it does not create
an intermediate list. So it is more efficient than 'reduce(func, args)'
variant. Supporting it in compiler in a sense is almost trivial:
most of code is present anyway to support '[i for i in l]' construct.
Supporting "func"/[args] in interpreter is harder because interpreter
parser is much more messy than Spad parser. But the future plan is
to replace interpreter parser by Spad parser...
