Not to forget scalar evaluation within strings:
"${\(<foo>)}"
as in:
perl -e 'print "Current time is: ${\(scalar localtime)}\n"'
(the parens could as well have been omitted)
as opposed to the array evaluation
"@{[<foo>]}"
as in:
perl -e 'print "Current time is: @{[scalar localtime]}\n"'
Note the obvious difference to:
perl -e 'print "Current time is: @{[localtime]}\n"'
