The constant form of the flip-flop only operates against $.. Ie. The line number of the current file being read. Hence the first loop below produces the output expected, but the second does not.

#! perl -slw use strict; while( <DATA> ) { print if 1..4; } for ( 1 .. 8 ) { print if 1..4; } __DATA__ line 1 line 2 line 3 line 4 line 5 line 6 line 7 line 8

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
