[R6RS] Making -> a valid identifier

[Michael Sperber]

Trying to revive this ...

My best shot so far is:

<peculiar identifier> -> + | - | ... | <strange identifier>
<strange initial> -> - | . | +
<strange identifier> -> <strange initial> <subsequent>*
  ... but excluding everything in <number>

(This also tries to satisfy Kent's request of allowing identifiers
starting with + or .)

The exclusion should still keep things indirectly regular, but with a
practical implementation path.

Alternatively, here's a more direct approach:

<strange identifier> -> <strange initial> <strange subsequent> <subsequent>*
<strange subsequent> -> <constituent, without i and n> 
	              | <special initial>
                      | <special subsequent>
<constituent> -> <what SRFI 75 says replaces <letter> > 

... but excluding just i and n seem really arbitrary and confusing.
