Yes, I plan to name the macro "loop". At least in R[67]RS, it won't
clash with locally defined variables named "loop". Thanks to the
rename facility of the R[67]RS module system, it can also peacefully
coexist with other loop facilities named "loop" as well.

As a loop is a basic construct, I don't think a distinguishing name
like "loop-of-marc" would be a good choice.
