sort!

Usage

sort! l
sort!(l, f)

Signature

sort!:

(%,(T,T) $\to$ Boolean) $\to$ %

Parameter	Type	Description
l	%	a list
f	(T, T) $\to$ Boolean	a comparison function

Description

Sorts the list $a$ using the ordering $x < y \iff f(x,y)$. The comparison function $f$ is optional if $T$ has TotallyOrderedType, in which case the order function of $T$ is taken.

Remarks

sort! does not make a copy of $l$, which is therefore modified after the call. It is unsafe to use the variable $l$ after the call, unless it has been assigned to the result of the call, as in l := sort! l.
