in reply to I don't use printf enough

I can see using it or not as a decision depending on what circumstance allows. Would the following also work, though?

print( join('', ('text text ', $obj->method1(), ' more text ', $obj->method2(), ' blah blah ', $obj->method3(), "\n") ) );

    Ummm. Unless $, is set to something besides undef, why join? print accepts a list just as easily as a single string.

    I often use a similar construct, like so:
    use constant DELIM => "\t"; my $fh = IO::File->new(">$filename") || die $!; print $fh join(DELIM, 'Col 1', 'Col 2', 'Col 3', ), $/; # And so forth

    Yes, I should use something like Text::xSV, but it currently doesn't do output.

[Corion]: GotToBTru: Yeah, I started a quick(ly implemented but slowly running) implementation of a program that would guess the "best" configuration (that is, least amount of changes) from my code, but then found that it stops parsing the source as soon as it ..
[GotToBTru]: sadly, it can't do anything about this
[Corion]: ... encounters sub foo($bar,$baz) {, which is something I like nowadays
[Corion]: GotToBTru: Yeah, that stuff is hard to do away automatically ;)
[GotToBTru]: yeah, you mentioned it could not handle signatures
[Corion]: And so far I like signatures and nobody has yet come up to me and screamed at me for implementing a source filter to handle them even on early Perl versions ;)
