reset
Resets ?? (one-shot match) operators so they can match again.
The ?? operator matches only once between calls to reset.
Without an argument, resets all one-shot matches in the current
package. With a character-range argument, resets only those in
variables whose names fall within the range.
This is a deprecated and rarely used feature. Returns 1.
Implementation status: Stub (no-op). PetaPerl does not
currently track ?? match state.
Synopsis
reset; # reset all ?? in current package
reset 'a-z'; # reset ?? in variables matching range
