how to pipe the output of one process to another using guile ?

[Samuel Barreto]

Hi everyone,

I was wondering how I could replicate the simple

        cat "my-toy-file.txt" | wc -l

using Guile ? I have been reading the POSIX Pipes and Default Ports
Guile manual entry very thoroughly but I could not wrap my head around
it. (I am not familiar with POSIX and all I am afraid …)

Thank you !
Samuel
