[Haskell-cafe] Unicode symbols in operators

[Niklas Hambüchen]

(I'm trying to improve Sublime Text's Haskell lexer.)

https://www.haskell.org/onlinereport/haskell2010/haskellch10.html says
  uniSymbol 	→ 	any Unicode symbol or punctuation

What is meant here, is "Unicode symbol" literally \p{Symbol} in regex,
or more?

So uniSymbol = \p{Symbol} | \p{Punctuation}

Thanks!
