Julia’s creators say they are greedy - so am I. I want to create a function g that accepts a list of arguments (I am trying with a named tuple), and passes it on to a function f. I have 3 requirements
- The user of g must provide “named arguments” as in “a=3”, for readability of the code calling g
- Arguments must be optional, with fallback on a default value
- and here comes the crunch: g must not be concerned with the details of this argument list.
Why would I ever want to do that? Well, in the real world, g does a bit of work behind the scenes.
struct T a b end f(;a=0,b=0) = T(a,b) g(foo,s...) = foo(s...) r=g(f,(a=2))
but splatting was clearly not intended for named tuples. Any ideas that do not involve metaprogramming?
I am knocking off for the day, but I am wondering if g could become a macro… metaprogramming-light.
