If it appears when executing "local", it was defined in the current
With no operands, local writes a list of local variables to the standard

Specifically, it foo was defined as a local in func1 and func1 calls
func2, "$foo" will be "usable" in func2 but foo will not appear when you
execute "local" from inside func2.
What is your use case for this question, please?
