in reply to How do I print a quotation-mark?

Use some other string delimter, such as single quote (') or qq (as in qq(...) or qq/.../):
print qq[And vroom said "Let there be nodes!" and there were nodes.\n] +;
Use a "here-document" syntax:
print <<"WALDO"; "Where is Waldo?" asked the creature? It replied "On the next line!" WALDO
