Hi,
I tested the expression below
and it doesn't work. Is there
some way to achieve that (i.e.,
turning an expression inside
parenthesis into an operator)?
2 `(flip (^^))` (3%4)
Another solution if you don't like defining extra (-|) and (|-)
operators is:
> ($2) (flip (^^)) (3%4)
The right section of function application is type lifting. The general
form of this construction is:
> ($x) (f a b c...) y z...
Which is equal to (f a b c... x y z...). That is, the construction lets
you raise any argument out to before the function, thus making the
partially applied function into an infix between |x| and |y x...|.
