Nonetheless, Perl folk do use that term, specifically.

"One thing that distinguishes Perl from other languages is its use of=20
sigils; the funny looking symbols placed in front of variable names. "

$ 	Scalar 	$foo
@ 	Array 	@foo
% 	Hash 	%foo
& 	Subroutine 	&foo
* 	Typeglob 	*foo


 >    Sigils have many benefits, not least of which is that variables=20
can be interpolated into strings with no additional syntax. Perl scripts=20
are also easy to read (for people who have bothered to learn Perl!)=20
because the nouns stand out from verbs. And new verbs can be added to=20
the language without breaking old scripts.
