I think the problem is that parsing of a = b is context dependent, either Expr(:=, ...) in normal cases or Expr(:kw, ...) after ; in function definitions and named tuples. And AFAIK there is no easy way to create a list of Expr(:kw) to splat after the ; except with the literal syntax :((; a = b, c = d)) but here we want to do it programmatically.
