Count characters in s that match pattern.
See if character c is in the pattern. Patterns:
See if character c is in the intersection of the patterns.
Finds the position pos of the first character in s that does not match pattern (in the terminology used by std.string.inPattern). Updates s = s[pos..$]. Returns the slice from the beginning of the original (before update) string up to, and excluding, pos.
Return string that is s with all characters removed that match pattern.
Return string where sequences of a character in s[] from pattern[] are replaced with a single instance of that character. If pattern is null, it defaults to all characters.
Contains the obsolete pattern matching functions from Phobos' std.string.
