I take your word that some old shells may have had initial problems with the $(), but does this hold true any more in practice in 2007? If I would compare the same thing with perl that &functions() is valid syntax as of Perl 2007, we would never change a thing move to remove the extra "&". From QA perpective in Perl's case the removal of "&" in front of function names is encourages because it make thinks more readable. I agree that `cmd` is widely recognized, but the other side of the coin might be that in $()'s case: - developers may not be aware of it, so they only use `` - they stick to what they has "always used" because they're afraid of a change (legend: "break thinngs...") - they might not be aware of how difficult it is to dinguish ` from '. Not everybody has eagle's sight; many have glasses to stare the tube. These should see the doctor; get better glasses? Back to the point. From QA perspective does "The Debian Project" not see any value of encouraging $() ? Jari -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
