In addition to what the others have said I also belive it to
be a matter of programming "style". One could have easily
stated the example as this:
foreach (@example) {
$unfeasibly_long_variable_name_I_should_know_better_really
+= $why_do_people_not_learn_to_break_lines / $_;
}
This way - the code still remains readable, maintainable without
needing to "figure out" where things begin and end.
So monks that post may consider this as an alternative to
"run-on" statements. This of course dos not apply to the
obfuscated code.
