You cannot do
use Module and assume it to have only
lexical effects.
use is handled at compile time.
You can do what you want at run time though, by using
require.
Something like:
if ($arg is a FILEHANDLE) {
require DBI::Pretty::File;
%hash = DBI::Pretty::File::read_stuff_from_file ($arg);
}
elsif ($arg is a XML datastream) {
require DBI::Pretty::XML;
%hash = DBI::Pretty::XML::read_stuff_from_xml ($arg);
}
I do get the feeling you are mixing OOP with procedurial coding
and getting the worst of two worlds. I would either make $arg
an object so I could do $arg -> read_stuff, or I'd make
a function, possible in a separate file (and module), so that I could
do %hash = read_stuff ($arg) and put all the reading stuff
from DBI::Pretty::File and DBI::Pretty::XML
and other modules in there.
