In any quoted string (
"",
'',
qq{},
q{}, etc.),
a double backslash must be interpolated as a single backslash, because a backslash is used to
escape the quoting character(s). This makes it possible to get the one character string
\ and the two character string
\', with
'\\\'' and
'\\', respectively.
Here-docs are the exception to this. One can always find a terminator, possibly several characters long, that doesn't appear within the string itself. Thus, backslashes are free to be regular characters in a here-doc.
I don't think you're missing anything; this is just how strings work in Perl.
