Module pl.strict
Checks uses of undeclared global variables.
All global variables must be 'declared' through a regular assignment
(even assigning nil
will do) in a main chunk before being used
anywhere or assigned to inside a function. Existing metatables __newindex
and __index
metamethods are respected.
You can set any table to have strict behaviour using strict.module
Functions
