For a long time there's been an odd disconnect between the official and
effective syntaxes of Scheme.  The BNF does not actually allow
an expression like "(+ 2 . (3))", but I can't imagine a Scheme that
would fail to accept it.

From what I understand, it is now typical for Japanese programmers writing
bespoke Java code to do so entirely (except for reserved syntax words)
in Japanese.  Making Scheme fully accessible to programmers worldwide
implies allowing Scheme programs (even the syntax, if you want) to be
written with identifiers in any language.  This will undoubtedly interfere
with the ability to easily read any piece of Scheme code, but it is IMHO
