Would this enable people to type something like
    wget -O - http:try.this.for.example.com/fun.mischief|guix repl -
and if so, can you suggest some options for automatic hash or signature
checking so that a paranoid could feel safe using a file pointed to
by a friend? 

(I know one can already do silly stuff ... :)

I was hoping for a concise option that would enable a standard way of doing
integrity/trust checks by the stdin bufferful within guix. (Which I guess implies
designing fun.mischief file syntax as some kind of container packet stream, with
individually verifiable packets -- what would that mean for input to guix repl?). 

Maybe a --paranoid option at the level of --dry-run or -n ?
(maybe configurable as default --paranoid=on :)

As far as avoiding file generation, a pipeline that needs file-size chunks to do
validation checks would only avoid file inode supply limits, right?
I guess YMMV per platform? IPC also has supply limits, IIRC.

Hm, what about an option for guix like
   guix  --trust-manifest="file-containing-sufficient-verification-info-for-what-happens-next" repl -
meaning e.g., sha256sum value for what would be passed via '-' and if that contains references
to other files etc., than hashes or signatures etc for everything entailed.
