Re^4: 2*pi*$r -- constant function without prototype

As long as your going to use ${} to interpolate vars into strings, which is generally a good idea. Then you can use constants in a similar way with a single extra '\' character:

use constant NL => "\012";;
print "fred${\NL}bill${\NL}";;
fred
bill
