in reply to What did you have to Unlearn

I had to unlearn that I can't program in English.

$ftp->mkdir( $dir ) and $ftp->cd( $dir ) unless $ftp->cd( $dir );

    Shouldn't that be something like...
    $ftp->cd($dir) or ($ftp->mkdir($dir) and $ftp->cd($dir));
    Technically, the most english way of writing the code (that actually works) is:
    $ftp->mkdir($dir) and $ftp->cd($dir)
    If you don't mind making the standard case having one extra file system access and the non-standard case having one less access.

      Try it! The first time you end up in the dir. The second time not. Because mkdir fails. Because the dir is already there. Ok, there are Server around, which go "Make a Dir? Is the dir there or not? So don't bother me with particulars!". There your tactic succeeds.
