You already have the parameter symbols in the method definition.

def my_method( pos, width, height )
    ...
end

my_method( pos: 10, width: 20, height: 30 )

The place you don't have them (at the moment) is with native C functions as
Ruby methods:

VALUE rb_my_method( VALUE self, VALUE arg1 )
{
    ...
}

Thinking aloud: would the argument order be taken care of at parsing time?

my_method( height: 30 width: 20, pos: 10 )

is reordered to:

my_method( pos: 10, width: 20, height: 30 )

or even:

my_method( 10, 20, 30 )
