Module::Load's interface is rather more heuristic than desirable. If your
input doesn't look like it could be a module (/[^\w:'/), it will require it
as a filename, if not it will try to convert it to a filename, first trying
with ".pm" appended and then without (resulting in a rather characteristic
double error). In the latter case if given arguments (or called as
autoload) it will also run the associated import method.

These are many different behaviors, that should really have  different
names (e.g. load_file and load_module), and TBH some of those behaviors
probably shouldn't exist. Module::Load is the sort of tool that will
usually work, but can sometimes magically do something confusing.
