Well it probably stands for uniform, but I guess both are true.

That looks great.

I don't have a problem with the feature (it actually looks great with the ctor
example you gave there), but it's hard to say what's expected when there's ZERO
documentation for UFCS in the spec, which is ridiculous since we've had this
feature for the last several years and it has just expanded in functionality
ever since. Even TDPL barely talks about UFCS, and calls them "pseudo members".

I really wish people who implement language features spent 10 minutes of their
time writing documentation about it. As it stands, it seems only compiler
hackers seem to know what language features actually exist and are expected to
work.
