That's what I originally thought about, but the thing is `]` in and of itself is not an operator while `>` is, so

    foo<bar, qux>corge>

"is" valid syntax while

    foo[bar, qux]corge]

is not. The former requires some sort of disambiguation, while the latter is not. Put an other way, in terms of syntax `[]` always parses the same way (with `[` is infix and `]` terminates it), there can be ambiguity between indexing and generics but it doesn't really matter for the original parsing.

For `<>` however, the parsing itself can be ambiguous as `>` could either be the terminator of an earlier `<` or it could be the infix `>` operator. That is where the issue lies, you can't know how to build the AST without either explicit disambiguation, or infinite lookaheads.
