in reply to Re: On Commenting Out 'use strict;' (errors)
in thread On Commenting Out 'use strict;'

For strict, I'd show them a simple example of mistyping a variable name and provide the two ways to "fix" the error: 1) correct the spelling of the variable name, 2) comment out use strict.
Of course, if their program is just missing the 'my' (and doesn't contain other bugs), 1) doesn't apply, and 2) shuts off the error messages, and generates the correct output.
