I never use multi-line strings in this form; instead I use the "here-document" form:
#!/usr/bin/perl
print <<EOF;
hello
world
EOF
Here the "<<token" is replaced by the string consisting of everything between the
start of the next line and the first occurrence of the token at the beginning of a
line (IIRC). Like this, you get substitution in the string (for character escapes and
variables); if you write
print <<'EOF';
hello
world
EOF
instead you get no substitution of escapes or variables; backslashes, dollar signs, at
signs etc are left untouched.
I find this a bit cleaner than looking for four matching pixels possibly pages below.
