Maybe there's another option (parens around the entire call, if it's at the start of an expression-statement?). Or just around the (template) keyword alone. There, that should enumerate all the possibilities :) -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.

Perhaps require parens: (template f<= ;int>)(a) or even (template f)<int>(= a). I did find myself wishing for something like this.

Parens would be a bit strange, since= they're currently an idiomatic way of disabling ADL. Maybe there's another= option (parens around the entire call, if it's at the start of an expressi= on-statement?).

Or just = around the (template) keyword alone. There, t= hat should enumerate all the possibilities :)
