new CGI is easily misunderstood. Some even suggest that you should write CGI::->new() to prevent CGI->new() being interpretted as main::CGI()->new(), which is possible. I'm not completely decided on that last point because I don't think it is supported in moderately old versions of Perl and I feel that I can usually avoid having functions that have the same name as modules that I use. I will probably convert to CGI::->new() before too long, though.

So let's consider: 

    my $q= new CGI;

[download]
What if you do this from a package? You probably have a new() method of your own and now you've (probably) done: 
    my $q= new( "CGI" );

[download]
I think there are also gotchas with regard to confusing precedence, but I don't recall them.

So many (including me) suggest that you always avoid "indirect object" notation. This might also apply to the standard: 

    print HANDLE "Stuff\n";

[download]
which should instead be written: 
    HANDLE->print( "Stuff\n" );

[download]
but I've not seen that point pushed much. I personally think that things will slowly migrate that direction, though.
