labelled fields

Hello, I need something like data Type = TCon String {lmtc::Maybe String} ... but this does not seem to be possible. Instead I have to waste identifiers: data Type = TCon {senseless::String,lmtc::Maybe String} ... Why? Are there any formal reasons against the above declaration? Or do I miss something? Thanks, Steffen -- Steffen Mazanek - www.steffen-mazanek.de - GPG: 791F DCB3 Haskell, that's where I just curry until fail, unwords any error, drop all undefined, maybe break, otherwise in sequence span isControl and take max $, id: (d:[])
