From what I\'m reading, $
is described as \"applies a function to its arguments.\" However, it doesn\'t seem to work quite like (apply ...)
in Lisp
If I look at your question and the answers here, Apocalisp and you are both right:
$
is preferred to parentheses under certain circumstances (see his answer)foo (bar quux)
is certainly not bad style!Also, please check out difference between . (dot) and $ (dollar sign), another SO question very much related to yours.
