Re: referencing a map produced from a function

On the whole, with some exceptions, the language design is othogonal, so if you can write $M($K) where $M is a map, then you can replace $M with any expression that returns a map, including for example a function call F(a,b,c)($K).

Of course in some cases the replacement expression has to go in parentheses.

There are a few exceptions: pseudo-operators like "?" whose operands are not general expressions, but are more restricted.
