No. I am always a little bit more cautios when using evals since you
the string passed into it could contain everything. You might not
expect that you could accidently delete files, just because you asked
for a class. I am probably careful at this from the time I did
CGI-Programming in Perl.
 
But the solution using Module::const_get by Minero Aoki looks much
nicer anyhow. And it is more correct too.

Then again I agree with matz that such a 'feature' is of doubtful
usefullness. I really don't see good reasons why it should be added to
the language.
