It's normal to run files in the current directory. Any function that wants to 
run arbitrary shell commands needs to be able to do that. Concerns were raised 
about not being able to run arbitrary commands, so the topic is relevant.

No, the shell command ". ." tries to run the . file as a script, assuming that 
PATH starts with ".:".

PATH can be relevant if a shell command name lacks slashes.

Admittedly it's weird to try to run "." as a shell script, but what can I say? 
This thread already went down that rabbit hole when the idea of running a 
command named "if" was raised. And "." is not a unique case here; for example, 
shqq won't run an executable named "break" either.
