Re: Solving >> issue in templates

[John Horigan]

What if you let the lexer emit the SHL token and have your grammar
accept '>' tokens or SHL tokens for closing template lists? The action
would check if SHL closed the template list and issue a call to the
lexer telling it to flush its input and insert another '>' token.
