I think this is a pretty dangerous one liner!

You should edit your post and strip at least the dangerous part from it, before someone tries to execute it.

Regarding your question, B::Deparse shows the transliteration as (indentation and linebreaks added for clarity)

tr
     ( -/:-@[-`{-})
     [`-{/" \-]
;

[download]

tr allows to define ranges with - , even outside alphabetic characters, such that you can translate

like `-{ in the "to" part becoming the alphabet

  DB<11> print chr($_),"" for ord('`')..ord('{')
`abcdefghijklmnopqrstuvwxyz{

[download]

update

flattening the "from" part 

  DB<16> print chr($_) for map {ord($_->[0])..ord($_->[1])} [' ','/'],
+ [qw(: @)],[qw([ `)],[qw({ })]
 !"#$%&'()*+,-./:;<=>?@[\]^_`{|}
