See also [https://github.com/JuliaLang/julia/issues/210](https://github.com/JuliaLang/julia/issues/210), a rather long-standing issue! We don’t have this feature yet, but it’s interesting to think about how it might work.

Also, as a minor aside, in typical terminology this is not called a template, but a function type or arrow type.
