Off-topic, I'm sure... but this line only gives me a compile error:

perl -le 's ssSss.s sSsSiss.s s$sSss.ss .$s\107ss.print'
[download]

Backslash found where operator expected at -e line 1, near "$s\"
        (Missing operator before \?)
Bareword found where operator expected at -e line 1, near "107ss"
        (Missing operator before ss?)
syntax error at -e line 1, near "$s\"
Execution of -e aborted due to compilation errors.

What gives...?
