To clarify - most of modern fonts do in deed have latin-greek-cyrillic (including the U+03BB lambda), but I was referring to the specific math symbols such as the U+1D6CC bold lam(b)da, which reside in the Supplementary Multilingual Plane (SMP). Those are indeed not present in my fonts, including Lucida Math and Adobe Mathematical Pi). cheers, Arnar ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

I was searching for what I thought was > the correct spelling. Same here. Another problem is font support.. none of the fonts on my system (and I have quite a lot) have these codepoints defined. One would have to open them in a font editor and copy the greek lambda. cheers, Arnar ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

All the operations on TMVars are atomic. I will second this. At the very least, if you only need atomic read/write operations you can use TMVars and make aliases that compose with atomically: takeMVar = atomically . takeTMVar putMVar = atomically . putTMVar etc. cheers, Arnar ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
