About the pull request

This PR fixes these messages for the OD lint:

Warning OD1002 at code/__pragmas.dm:15:26: Warning 'TooManyArguments' does not exist
Error OD0000 at code/datums/global_variables.dm:127:30: attempt to reference r-value
Error OD0000 at code/datums/global_variables.dm:369:44: attempt to reference r-value

TooManyArguments was replaced with InvalidArgumentCount which should already be an error. The other two errors are regarding initial not working on globals, which it does not appear to.

Explain why it's good for the game

Passing checks is good.
