[stringtemplate-interest] Fwd: How best to do recursive hetero template calls?

[Gerald Rosenberg]

Hi Ter,

Recursive hetero template calls (given /node.type/ is the literal name 
of a template):

TypeA(node) ::= <<
     // Prefix code for <node.type>
     ...
<node.children:{ node | <(node.type)(node)> }>
     // Suffix code for <node.type>
     ...
 >>

While it works well, turns out practical use is somewhat limited in that 
it renders as just one big blob of code|text.

Wonder if any thought has been given to allowing ST to render to a 
string array, maybe using some template level flag to mark when to 
switch to generating to a new array slot?  Would add flexibility in the 
subsequent stitching together of the content.

Best,
Gerald
