What makes the choice of < > for template parameter bad appears when someone tries to nest templates. a<b<arg>> and now a means greater becomes a shift right. That's one of the reason that it you had a genious ideo to find domething else in D a(template params)(runtime params) at declaration a!(template params)(runtime params) at invocation with the type deduction and parenthesis omission making often even disappear completely the template syntax. thank you
