The main trick here is that the substitutions and transliterations use letters as delimiters.
For example the following are equivalent:
s/lt/t/;
s altata;
Unrolling your code gives the following:
print unless s//\n&E vtuEAopuifs&PfsmEHbdlfs\n\n/ &&
y/&b-z&/&a-y&/ &&
y/E &/ J /d &&
0
The results of the three transformations are:
&E vtuEAopuifs&PfsmEHbdlfs
&E ustEAnother&PerlEHacker
Just Another Perl Hacker
