=over =item reset EXPR =item reset Generally used in a C block at the end of a loop to clear variables and reset C searches so that they work again. The expression is interpreted as a list of single characters (hyphens allowed for ranges). All variables and arrays beginning with one of those letters are reset to their pristine state. If the expression is omitted, one-match searches (C) are reset to match again. Resets only variables or searches in the current package. Always returns 1. Examples: reset 'X'; # reset all X variables reset 'a-z'; # reset lower case variables reset; # just reset ?one-time? searches Resetting C<"A-Z"> is not recommended because you'll wipe out your C<@ARGV> and C<@INC> arrays and your C<%ENV> hash. Resets only package variables--lexical variables are unaffected, but they clean themselves up on scope exit anyway, so you'll probably want to use them instead. See L. =back
