Curly brackets are comments!

That could be a possibility as the compiler could then correctly handle the
field names, however it would have an ambiguity with typecasts until the
colon.
Though that would be solvable...

> rec := @(x: 1; y: 2; z: 1)

@ would be nonsense as that would denote a pointer.

Well, feel free to develop a patch, maybe it'll be accepted. I have other
fish to fry in the meantime.
