It's not pretty, but I used:

\newcommand\atl{-\!\!\!\prec}

Hope that helps.

Hello,

I want to typeset Haskell code using arrow syntax with LaTeX in math mode
(using lhs2TeX and polycode.fmt).  However I don't know how to produce a nice
LaTeX math mode equivalent for -<.  Does anybody have an idea what to do at
this point?

Best wishes,
Wolfgang
