Hi,
For a bit of holiday fun, I want to present a Rust implementation of
Knuth's man-or-boy <http://en.wikipedia.org/wiki/Man_or_boy_test>
compiler test. Can this be improved? Here's
<http://rosettacode.org/wiki/Man_or_boy_test> how it looks in other
languages.
Right off the bat, I would say that would be prettier if we had argument
auto-borrowing
I'm again pretty nervous about this, because this is one of the
much-maligned features of C++ references.
if invocation operator would auto-deref
I think I'm OK with this.
and if closure
assignment was in scope to be captured inside the closure itself
(wouldn't have to do dummy init of the B var).
This would prevent the useful `let mut foo = foo` pattern.
