The difference between QMagneQQ and QW in perl

In perl, qjournal, QQ, and QW are similar identifiers. They said respectively:

Q is equivalent to single quotation marks, such as:

$word = Q (World)

It is equivalent to:

$word = 'World'

Qq is equivalent to double quotation marks and can interpolate variables.

$word = qq (World)

Equivalent to

$word = "World"

Qw stands for separating elements with spaces to get a list
