    Summary: Vyper has incorrect re-entrancy lock when key is empty string

    Details: ### Impact Locks of the type `@nonreentrant("")` or `@nonreentrant('')` do not produce reentrancy checks at runtime. ```Vyper @nonreentrant("") # unprotected @external def bar(): pass @nonreentrant("lock") # protected @external def foo(): pass ``` ### Patches Patched in #3605 ### Workarounds The lock name should be a non-empty string. ### References _Are there any links users can visit to find out more?_
