It seems that giving > it a new interpretation could confuse people. `$' only appears to have this behavior, according to the regcomp documentation, when the REG_NEWLINE flag is passed: : `REG_NEWLINE' : Treat a newline in STRING as dividing STRING into multiple lines, : so that `$' can match before the newline and `^' can match after. : Also, don't permit `.' to match a newline, and don't permit : `[^...]' to match a newline. : : Otherwise, newline acts like any other ordinary character. - Maciej Stachowiak
