[stringtemplate-interest] mapping templates

[Terence Parr]

ooops, what about args that are part of the map? here's an ANTLR  
example usage:

<bitsets:bitset(name={FOLLOW_<it.name>_in_<it.inName><it.tokenIndex>},  
words64=it.bits)>

I want to set some args as well as the "it".

I do it again here:

<foo:parameterScope(scope=it)>

But, scope is only arg so it's same as:

<foo:parameterScope()>

or

<parameterScope(foo)>

So, anybody else use the args in map call?  I'm thinking it's  
confusing and we should remove.  E.g., in what context is "it"  
evaluated above?

I could rephrase as

<bitsets:{b | <bitset(name= 
{FOLLOW_<b.name>_in_<b.inName><it.tokenIndex>}, words64=b.bits)>}>

so we don't need I guess. Objections?
