If you don't want to declare with our or use constant (maybe also take a look at Readonly, but that seems to exact a speed penalty (Update: see thread Module Readonly, esp. the most recent reply)),  $::myVar is a little bit less typing than  $main::myVar (well, at least as long as you're in the  main package). 

>perl -wMstrict -le
"*myVar = \3.14159;
 print $::myVar;
"
3.14159
