in reply to from array to hash with grep

Since it is fixed-length scanning, we can use pack() and unpack():
my @inp = ("abc_A_bla", "abc_B_bla", "abc_C_bla") ; print "@{[ keys %{{ unpack '(x4 A A4)*', pack( '(A*)*', @inp) }}]}";

Corion watches from the sidelines. Or rather, from behind, as my system only gets output from that process and my programs adhere strictly to the GIGO design principle.
[erix]: ah, that's nice to hear Corion :)
[Corion]: erix: Yeah, the sad thing is that all I can do is document things, so I can point fingers when the auditors come :-/
