Broadcasting tuples in Julia 0.5

[giordano]

Julia master has the ability to broadcast tuples (PR JuliaLang/julia#16986), which is incredibly handy. Is it possible to backport this feature to Julia 0.5 with Compat?

[wsshin]

I want this capability as well!

I don't think it's practical to backport (cc @pabloferz).

There's a one-liner on that PR that could be backported to 0.5

@inline broadcast{N}(f, t::NTuple{N}, ts::Vararg{NTuple{N}}) = map(f, t, ts...)

This would probably be enough to satisfy most of people's needs when broadcasting over tuples. Unfortunately, handling mixtures of arrays, tuples and/or scalars is too disruptive to be back-portable.

[giordano]

@pabloferz for my use case that should do the trick.

Has Julia 0.6 lost the ability to broadcast tuples? The following does not work

x = y = 0.
x, y += 2.
