[stringtemplate-interest] What compiles to : Bytecode.INSTR_LOAD_ATTR ?

[Udo Borkowski]

Hi Colin,

instead of 

>         group.defineTemplate("main", "string", "{<string.q>}");

just write 

>         group.defineTemplate("main", "{<string.q>}");


and it will generate an INSTR_LOAD_LOCAL

This method call gets invoked when the Interpreter runs into Bytecode.INSTR_LOAD_ATTR. My problem is that my simple test never generates this bytecode. It only generates Bytecode.INSTR_LOAD_LOCAL.
