Hi,

I know about eval "string" and do "filename.pl"

Now I have a stream that produces data blocks, something like a function that returns one data block per call. I don't want to store all the data in memory to do a string eval. So I thought of something like 

do sub {...} # the function returns one data chunk per call

(I know this does something else and is deprecated)

So, how about this? 

do FILEHANDLE # FILEHANDLE is opened with a special PerlIO
              # layer that calls sub {...} on read.

Is that possible?

Thanks,
Torsten
