In Haskell we write `f` in order to infixify the identifier f. In ABC the stuff between backquotes is not limited to an identifier, but any expression may occur there. This would allow one to write e.g.
xs `zipWith (+)` ys
In general <expr1> `<expr2>` <expr3> => (<expr2>) <expr1> <expr3>
I think it is a small extension to Haskell, which does not break anything existing, and provides yet another opportunity to beautify one programs, especially in combination with programs like lhs2TeX.
There is one problem with this: it doesn't nest, you can't tell an opening from a closing backquote, which can cause problems when transforming or rearranging code. Possibly `(<expr>)` and the existing `<identifier>`? -- flippa@flippac.org 'In Ankh-Morpork even the shit have a street to itself... Truly this is a land of opportunity.' - Detritus, Men at Arms
