Re^6: Indirect variable expansion

You would still have to export it to see it in the perl process:

$ export M=MyMod
$ perl -M$M -E 'say $ENV{M}->VERSION'
$ unset M

Or just do it in a subshell to keep your environment clean:

$ (export M=MyMod; perl -M$M -E 'say $ENV{M}->VERSION')

yes my point was to avoid the export, because it IS visible inside the Perl process `~$ M=whatever perl -E'say $ENV{M}' whatever` [download] unfortunately a dynamic `use` inside the process is not less complicated than the solutions already shown (eval or Ikegami's `if` `1` trick) Cheers Rolf _{(addicted to the Perl Programming Language :) see Wikisyntax for the Monastery}	[reply] [d/l] [select]
