That’s not possible, unfortunately. Currently, the list is merely
converted to a string, so (list "sample.bam" "hg38.fa" "abc") becomes
the string “sample.bam hg38.fa abc”. For singleton lists that’s exactly
what you want, but it’s not great for longer lists.
I thought about adding support for selectors, but I don’t know if I
should. Maybe it would be better to allow for named inputs instead,
which would result in process-local bindings.
This would probably require changes to the records macro that we took
from Guix. I’d prefer that over implementing a small language in a
reader macro.
