Indeed.

Actually I think it's more fundamental than that.  The compilation
process tries, generically, to find a path through the language tower
path from the source language to the target language.  There is nothing
bytecode-specific in (scripts compile), except for a couple default
target languages.

It seems to me that the value of the target-type fluid at the time that
`compile-passes' is called should be what determines the compilation
path and target-specific settings.  For example, to continue the ARM
compilation example, perhaps it would cause a different target language
to be selected.

Dunno.  All of that could just be too complicated, and maybe you are
right.

Andy
