[antlr-interest] Stringtemplate : conditional expansion based on template type

[Bill Andersen]

Hi folks

I'd like to do something like the following with these template definitions

A() ::= <<
>>

B() ::= <<
>>

C(template_arg) ::= <<
// if value of template_arg is an instance of A
//    expand this way
// else if value of template_arg is an instance of B
//    expand some other way
>>

Question - is querying the type of a template passed as a parameter a legitimate predicate in an <if ...> construct?
