We should probably just remove these but I cba looking through them to check right now

• TEST FAILED: BrokenTests/Indent/closing_brace.dm
• TEST FAILED: BrokenTests/Expression/escape_identifier.dm -- this one works with the bots in discord, but not the test framework
• TEST FAILED: BrokenTests/Procs/allow_null_argname.dm
• TEST FAILED: BrokenTests/Statements/For/var_only.dm
• TEST FAILED: BrokenTests/Statements/For/var_only_typed.dm
• TEST FAILED: BrokenTests/Statements/For/var_only_as.dm
• TEST FAILED: BrokenTests/Statements/For/fakeout4.dm
• TEST FAILED: BrokenTests/Const/ConstSort.dm
