I always thought \l lowercased, and \n was newline....

On my system, "\l" isn't anything.

printf "\\l = %d\n", ord "\l";
printf "\\f = %d\n", ord "\f";
print "\\l: [\l]\n";
__END__
\l = 0
\f = 12
\l: []

Try this:

$ perl -e 'print "\lTook \LNow Is The Time\E For All Good Men\n";'
took now is the time For All Good Men

Update: I finally found that reference table. It's in perlop. Quick recap:

The following escape sequences are available in constructs that 
interpolate and in transliterations.

 \t          tab             (HT, TAB)
 \n          newline         (NL)
 \r          return          (CR)
 \f          form feed       (FF)

The following escape sequences are available in constructs that 
interpolate but not in transliterations.

           \l          lowercase next char
           \u          uppercase next char
           \L          lowercase till \E
           \U          uppercase till \E
           \E          end case modification
           \Q          quote non-word characters till \E

If "use locale" is in effect, the case map used by "\l", "\L", 
"\u" and "\U" is taken from the current locale.
