Are you sure? It'd break a lot of existing code. And some cases would be 
hard to fix.

ie, the simple case of:
expectsoneargument(returnstwoarguments())

is easy to fix:
expectsoneargument((returnstwoarguments()))

But what about:
expectsfourarguments(returnsmanyarguments())

The only solution I can think of is:
local p1, p2, p3, p4 = returnsmanyarguments()
expectsfourarguments(p1, p2, p3, p4)

... personally I greatly prefer the existing Lua way.
