Re^2: Converting to boolean

To further elaborate on hv's excellent response, I often want to know for a fact that a value is explicitly TRUE or explicitly FALSE. Some situations:

Talking with another program through an interface
Passing values through an API, like HTML::Template
Dealing with people who are cute and like to use the zero-but-true value "0E0"
Making it explicit to the maintainer (who is usually me, 6 months down the road) exactly what this is meant for
Doing validation checks so that I can be certain something is useful only in a boolean context.

It's a minor point, but it's those details that I find separate the beginner from the expert.

I shouldn't have to say this, but any code, unless otherwise stated, is untested

Do you know where your variables are?
