Perl was immensely popular, but it isn't necessarily enough to qualify for the personal "bubble" of languages one learns. It was a good choice of proven, general purpose interpreted scripting language for you in a time when Perl competed with AWK and shell scripts, but in the 1990s I used mainly C and C++ before adopting Java quite early and almost exclusively; when I later decided to learn some proven, general purpose interpreted scripting language Python was my obvious choice: more advanced than Perl 5 and more popular than Ruby.
