`data-inputs` is often a list, say the genome (genome.fa) and the
sequences (R1.fq and R2.fq); then the procedure uses each as e.g.
my-tool -i genome.fa -1 R1.fq -2 R2.fq
Personnally, I find the Snakemake notation clear:
input:
genome = genome.fa
seqA = R1.fq
seqB = R2.fq
shell:
my-tool -i {input.genome} -1 {input.seqA} -2 {input.seqB}
Well, I do not know which will be the best design.
process-local bindings with a "big let"?
procedure-local binding with let?
read macro with which "syntax"?
etc.

Hum? ok...
I am not sure to see what should be the final result?
In any case, the string interpolation already improves a lot compared
to the string-append. :-)
All the best
