Just so. If the *intent* of the code is to remove the first three elements
from @_ and assign them to variables[*] isn't the clearest way to express the
intent just to do:
my ($a, $b, $c) = splice (@_,0,3)
It seems to express the *exact* semantics desired [remove the elements from @_
and assign those to the vbls), and to my eye does it more clearly than (shift,
shift, shift) does.
[*] NB: this has *different* semantics than doing my ($v1, $v2,
$v3) = @_ -- I'm assuming here that the modification to @_ is
actually necessary [if not, then it is not bad form on syntatic
grounds, but because it is doing something unnecessary and
potentially confusing].
