The idea is to introduce a grammar hack that notices `a++b` and evaluates it with identical semantics to `a+ +b`. C++ used a similar trick to allow `Foo<Bar<T>>` in addition to `Foo< Bar<T> >` for nested template application, because it previously conflicted with `>>`. For instance, consider `Foo<Bar<T>> name(arg);`: it used to be parsed as `(Foo < Bar) < (T >> name(arg));`, but they made a breaking change to make it parse as a variable declaration of type `Foo<Bar<T>>` instead, invoking the type's constructor with `arg`. I was suggesting a similar hack, just in this case taking advantage of something that is currently invalid.
BTW, I'm no longer behind my suggestion, and was never strongly in favor of it to begin with. ----- Isiah Meadows cont...@isiahmeadows.com www.isiahmeadows.com On Tue, Jul 9, 2019 at 2:50 PM ViliusCreator <viliuskubilius...@gmail.com> wrote: > > Lexer already sees `++` as operator, not `+` operator**s**.
