Golang proposal: spec: function aliases

Proposal Details

Go currently does not support function aliases. However, you can simulate function aliases using wrapper functions.

func X(args) { package.FuncX(args) }

This approach has the negatives of verbosity.

or through variable assignments

var X = somepackage.FuncX

This approach has the negatives of access to X being dynamic and the cost associated with that (eg. escape analysis, harder to inline etc.)

I propose the following succinct syntax similar to type aliases to improve upon the var X = .. form.

func X = somepackage.FuncX

Regarding generics - if FuncX is a generic function then X would be one as well.

Currently var X = somepackage.FuncX doesn't work when FuncX is generic.
