In the guile shell you can use

,expand (foo 1)

to see what it expands to.

Also see

,h compile

R7RS vs. R6RS isn’t that big of a difference in Guile, because it mostly
supports both and you can mostly use either of them.

R7RS is cleaner is some ways and managed to re-unite some of the Scheme
implementations (that were split between R5RS and R6RS). So knowing R7RS
means that you can make your code run in a much larger number of
domains, and you can keep many of your skills even when moving from
mostly server-side webdev (i.e. Chicken or Guile¹) to embedded (Chibi),
or to shipping binaries(i.e. Gambit or bigloo), or even Java/JWM (kawa),
or to others (see https://ecraven.github.io/r7rs-benchmarks/).

Why Guile? https://www.draketo.de/software/guile-10x
Why others? https://wingolog.org/archives/2013/01/07/an-opinionated-guide-to-scheme-implementations

¹: partially moving into clientside via Guilescript or others:
