Interesting! My own (subconscious) guidelines mean nesting is almost
absent; for a start, most subprograms are fairly small.

It always worries me when a nested subprogram makes uplevel references
to its parent's variables.

I imagine that most of us would regard a main program all of whose
called subprograms were nested inside it (recursively) with horror.

That said, completely forbidding declare blocks is going a step too far!
