Data Types Issue 30: Add Bag.literal
Introduction
Why doesn't BAG have a ".literal" property?
Proposal: I guess a simple literal would just be the one for list. Another literal form could allow for numbers too. Something like:
"[" { <int> <T_literal> } "]"
Discussion
I like the form with the number. But perhaps the number wants to be optional and distinguishable in a BAG<INT>? Attempt at defining the exact attribute grammar. Gschadow 18:04, 7 June 2007 (CDT)
BAG<T> : "[" sequence "]" { $.equal($2) };
sequence : sequence BXIT<T> { $.contains($1).and($.congtains($2)) }
| BXIT<T> { $.contains($1) }
;
BXIT<T> : T "(" INT ")" { $.equal(((T)$1)).and($.qty.equal($3)) }
| T { $.equal(((T)$1)) }
;
