I would generalize this for *ANY* programming languages.  It's always
better to declare variables before using them.

Forty+ years ago when I was writing FORTRAN programs, the first thing I
would do was declare all variables starting with [A-Z] to be logical, then
explictly declare things I wanted to use as REAL, INT, etc.  This didn't
keep FORTRAN from automagically making variables appear when I made typos,
but it would quickly get syntax errors as most operations on logical
variables were illegal.
