Quoting karczma@info.unicaen.fr:
"Widely accepted" is a widely accepted relativism... I am also annoyed by the precedences 0,1,2, ...,9, etc.
Why not 10, 20, 30,... ??
I _think_ we had this back around Haskell 1.1 (which I never used, but early Gofers also had it). Moreover, operators could also have arbitrary "fixity" (prefix, infix, postfix).
I'm not sure why this feature was dropped,
Because of readability I don't plead for arbitrary "fixities", I think the current solution of infix operators in Haskell is enough. There is really no advantage of "n !" over "faculty n".
There is a good argument for 'distfix' i.e. bracketing operators, IMO. You could define your own if_then_else: `if cond `then` truebranch `else` falsebranch end` (Syntax, terminology, and example stolen from "Macros and Preprocessing in Haskell", (1999) by Keith Wansbrough, see http://citeseer.ist.psu.edu/wansbrough99macros.html) Ben
