D parameters don't work this way. You cannot specify a parameter by name.
There are tricks you can use, such as structs with initializers, but the
result is probably not what you want.
No? That was different language then :(
Why it isn't allowed? Implementing that would be just about checking if
all required parameters are filled and make something with parameter
name / local function variable conflict. It would be nice a little nice
thing...
Or maybe lack of this feature pulling programmer out from throwing into
function 10 rarely used parameters? Would be a bad thing? What are
limitations for parameter number? There are any?
Lastly, what's the most preferred way of adding many rarely used
parameters into function? Been thinking about adding struct for them but
it's probably not efficient. Been thinking about variadic solution, but
that's just ugly since I hide possible solutions from programmer. I can
make solution stateful in the meaning of adding parameters one by one
because it's a method... I don't like this solution too. Named
parameters would be great but... absent. As You probably understand
adding foo(,,,,,,,,,bar,,,) isn't proper solution too :) Any hints?
