The other approach is to

BEGIN {
  eval "use $string \@imports; 1" or die "Failed lazy use(): $@";
}

Er. pfaut already said this. Sorry. :-)

Update:

As merlyn said below. You need to be real careful that $string is completely under your control. You dont want to be reading it froma file for instance. At least not without some serious data cleaning first.
