perldoc -f use tells you the following:

Imports some semantics into the current package from the named module, generally by aliasing certain subroutine or variable names into your package. It is exactly equivalent to 
    BEGIN { require Module; import Module LIST; }

except that Module *must* be a bareword.

So, you can easily do it like the following:

my $module = "CGI"; 
$module->require;
$module->import;

Update: Fixed the ugly bug I introduced. Thanks to tomhukins for spotting it.

Update 2: I should test before I promise broken things as fixed. See my reply to edan further down
