single-value tuple destructuring syntax?

[StefanKarpinski]

This works:

julia> (x,) = m.captures
("capture",)

but this doesn't:

julia> x, = m.captures
syntax error: extra input after end of expression

Would it make sense to allow this slightly odd syntax for destructuring a single value from a tuple?

eew, that's strange.

[StefanKarpinski]

You mean the syntax or the difference between with and without parens?

[JeffBezanson]

a, = b looks strange, and might be difficult to parse.

[StefanKarpinski]

Ok... we'll take that as a "no" :-P

[JeffBezanson]

well, most important thing is to decide if we want it. if people really want it i can probably make it happen. i don't really care either way though.

[StefanKarpinski]

Let's skip it. Seems too weird. If this becomes something people clamor for, we can reconsider.
