New submission from Ralph Corderoy:
https://docs.python.org/3/reference/lexical_analysis.html#identifiers has a
grammar.
identifier ::= xid_start xid_continue*
id_start ::= <all characters in general categories Lu, Ll, Lt, Lm, Lo,
Nl, the underscore, and characters with the Other_ID_Start property>
id_continue ::= <all characters in id_start, plus characters in the
categories Mn, Mc, Nd, Pc and others with the Other_ID_Continue property>
xid_start ::= <all characters in id_start whose NFKC normalization is
in "id_start xid_continue*">
xid_continue ::= <all characters in id_continue whose NFKC normalization
is in "id_continue*">
I struggle to make sense of it unless I remove `xid_continue*' from
`xid_start's definition.
I suspect it ended up there due to cut and paste.
