Bah. meant to add that it might be logical for
<chaim> =~ /RFC/
to seek to the beginning of the file before it starts
<chaim> =~ /\GRFC/gc
carries on from the previous position and doesn't seek back to the beginning
(or otherwise throw all the buffered data away)
Which effectively makes pos analogous to seek/tell.
So do we get rid of poss and seek() our scalars? :-)
It also allows the possibility of pos on file handles being fsetpos/fgetpos
Maybe that should have been an rfc 3 months ago, and really doesn't even
matter if perlio obsoletes stdio and internalises stdio's distinction between
text and binary streams.
BTW I am serious about needing a /gc not to chuck the buffered data.
It makes something like
@found = <chaim> =~ /RFC +(\d+)/;
not spend time stacking a lot of data back that's only about to be discarded.
But this isn't internals really, is it? I'm miles off topic.
