At this I am stumped.
$metatags is a scalar variable; the name is plural, because (as is
apparent the concatenation assignment operator below) it is to contain
all the metatags to be relocated, with the newline character as the
delimiter.
q appears to be a quoting operator, with delimiters { and } .
So, in this line of code, it appears that metatags is declared and is
initialized to the null string.
I am puzzled as to why it is necessary to initialize the variable to
the null string, unless the concatenation operator fails when
attempting to concatenate a string to an undefined scalar.
I also am puzzled as to why the curly braces are used as delimiters
for the null string.
Finally, I am curious as to why it would not be sufficient merely to
write:
my $metatags = ''
