The English module provides cumbersome aliases for
the built-in variables for prodigious typists with a visceral dislike
for nonalphabetic identifiers (and a visceral
like for the Caps Lock key). As with all
imports, these aliases are only available in the current package. The
variables are still available under their real names. For example,
once you use this module, you can use
$PID if $$ bothers you, or
$PROGRAM_NAME if $0 makes you
queasy. Some variables have more than one alias. See Chapter 28, "Special Names", for a complete description of all
built-in variables, along with their English
aliases.
