Question

Answer 1

Some people prefer ([: f g)to f@:gfor readability, perhaps because they are more common, although they f @: gperform the same distance without parentheses.

I'm sure I saw cases where it mattered to the result, but I can't remember them now. Perhaps others will be able to come up with examples in which they differ.
