Unless I'm completely mistaken, the above grammar will consume a single
NAME token ONLY ('name' is the start rule, and accepts exactly one
TK_NAME).

Try again with '%start with_possible_parameter_list' after your %type
lines, or with 'with_possible_parameter_list' as the first rule in the
grammar.
