Many times one must create a variable before a function call:

A new an improved technique, which consolidates the two lines
in to one is to automatically have the compiler define the
variable:
foo(x = 3);
writeln(x); // x was implicitly created in this scope by foo.
Couldn't you do what you need to do with UFCS and possibly a tee
function if you need to add things like writeln into the chain
that don't pass the data on?
