[julia-users] Is there an idiomatic way to discard values returned from a function

[Gray Calhoun]

Hi everyone, if a function returns multiple values, is there an idiomatic 
way to discard all but (say) the 3rd value returned? For example:

f(x, y, z) = return x^2, y^3, z^4
_, _, v = f(1, 2, 3)

expresses the intent to only use the third value returned, but surely is 
inefficient.

Thanks!
