Rawlen

rawlen( tbl )

Get the length of a table, bypassing metamethods

tbl

The table whose length to retrieve.

When creating things like custom containers, one often overrides the __len metamethod with custom code, but might then need to check the true length of the underlying table without going through that override. This can be done with rawlen().
