[Perl] suppression d'une valeu d'un hash

Hello,

extrait de perldoc perlfunc

delete EXPR
Given an expression that specifies a hash element,
array element, hash slice, or array slice, deletes
the specified element(s) from the hash or array.
In the case of an array, if the array elements
happen to be at the end, the size of the array
will shrink to the highest element that tests true
for exists() (or 0 if no such element exists).

Returns each element so deleted or the undefined
value if there was no such element. Deleting from
$ENV{} modifies the environment. Deleting from a
hash tied to a DBM file deletes the entry from the
DBM file. Deleting from a "tie"d hash or array
may not necessarily return anything.

Deleting an array element effectively returns that
position of the array to its initial, uninitial-
ized state. Subsequently testing for the same
element with exists() will return false. Note
that deleting array elements in the middle of an
array will not shift the index of the ones after
them down--use splice() for that. See "exists".
.....
#! /usr/bin/perl -w
%hash = ("key0" => "val0", "key1" => "val1", "key2" => "val2");
delete($hash{"key1"});

devrait faire l'affaire
