Features:

• The match time is linear in the length of the input string
• Regular expressions are (optionally) compiled at compile-time
• Captures all group repetitions (not just the last one)
• Unicode level-1 support
• Descriptive error messages
• Supports matching at compile-time (Nim +0.20)
• PCRE syntax and semantics
