[Bioperl-l] Speeding Up File Access

There was a recent article at PerlMonks.org about speeding up file IO:
One thing that caught my attention was the use of the :raw pragma on
filehandle creation to explicitly prevent handling of Unicode text. In the
example given this cut file IO times in half for a 3 GB file.
open (FH, '< :raw', $filename);
instead of just:
open (FH, '<', $filename);
I tried to look at Bio::Root::IO to see if an option for using this (or an
equivalent) was already implemented, but couldn't see one.
Is this something worth submitting a patch for? Would it be useful for
things like UniGene, LocusLink, BLAT, and Blast parsers or can these files
contain Unicode in them somehow?
