Dhruv Manilawala 7cb2619ef5 Add syntax error for empty type parameter list (#12030) ... ## Summary (I'm pretty sure I added this in the parser re-write but must've got lost in the rebase?) This PR raises a syntax error if the type parameter list is empty. As per the grammar, there should be at least one type parameter: ``` type_params: | invalid_type_params | '[' type_param_seq ']' type_param_seq: ','.type_param+ [','] ``` Verified via the builtin `ast` module as well: ```console $ python3.13 -m ast parser/_.py Traceback (most recent call last): [..] File "parser/_.py", line 1 def foo[](): ^ SyntaxError: Type parameter list cannot be empty ``` ## Test Plan Add inline test cases and update the snapshots.		2024-06-26 08:10:35 +05:30
