If tt(BASH_REMATCH) is set, then the array tt(BASH_REMATCH) will be set instead of tt(MATCH) and tt(match). + +Note that the tt(zsh/regex) module logic relies on the host system. The +same var(expr) and var(regex) pair could produce different results on different +platforms if a var(regex) with non-standard syntax is given. + +For example, no syntax for matching a word boundary is defined in the POSIX +extended regular expression standard.
