PerlNET will treat an int64 as a scalar, so I guess I still don't
understand your usecase.

Please don't bless arbitrary references into PerlNET internal classes.
They are intentionally undocumented and their implementation is subject
to change between releases. What are you trying to accomplish?

Yes, PerlNET will call ToString() on .NET objects if you use them in a
string context. It is the Perlish thing to do: treat them as a string in
string context and treat them as a number in numeric context. Actually,
PerlNET even handles boolean context specially. It is supposed to "do
what I mean" automatically.

Of course there is a limit on what Perl can do with int64 values in
numeric context, as Perl numbers don't have the same value range. We
have been thinking about implicitly converting them to Math::BigInt
objects if they cannot be represented accurately in either integers or
floating point numbers. Is this what you expect to happen?

Well, according to your bless statement above, it is an undefined value...

Can you provide some more information? Ideally a complete little sample
program that show the problem?

Sorry, I still don't understand what you are trying to do. Don't try to
push PerlNET into the strongly typed language corner. It tries to stay
as close as possible to being dynamically typed and make decisions at
runtime based on actual types of variables at that point in time.

I'm very interested to learn if there is a gap in things you can do with
PerlNET. But I still don't get the problem. So please show me a complete
sample. Show me how to do something in C# and explain why you can't do
it in PerlNET.

Cheers,
