Hmm. Your approach make 'load' configurable so that it can use
different 'read' procedures. Wouldn't it be more natural to make
'read' configurable to parse different syntaxes?
'load' is only a thin wrapper around 'read' and 'eval' (basically, a
repl without the 'p'). The real meat is in 'read' (syntax) and 'eval'
(semantics). So, if we want to customize the syntax, I'd say 'read'
is the place to do it. Then all users of 'read' would automatically
use the new syntax, not only when reading code in 'load'. (That's one
big point of Lisp, that the data and code syntax are the same.)
However, making the read procedure used by 'load' configurable can't
hurt, I think.
