syntax appears in an op form, crashing the expander with infinite
recursion at program load time, before the code is run.
* eval.c (transform_op): The fi == var check to handle a
trailing op variable in the dot position of a form
needs to ensure that it really is @<num> type var, and
not the @<sym> type for instance.

Explicitly specifying @rest using (op ... . @rest)

or @<num>.

Added lazy-stringp. Changing names of length-str-{gt,ge,lt,le}
to be consistent with the >, >=, < and <= functions.
* lib.c (lazy_stream_func): Greatly simplified implementation.
The lazy list now continues by means of recursing via
an optimized version of lazy_stream_cons called lazy_stream_cont.
The environment structure is simplified to just hold the next item,
rather than a pointless list. The pointless setting of lcons->lc.func
to nil is also removed; this is always done by the caller.
(lazy_stream_cont): New static function, similar to lazy_stream_cons,
but optimized by not consing up a new function and new environment
cell.
(lazy_stream_cons): The environment for the update function
is simplified to just a single cons.

arguments to plus, so that the from object is on the left. This
change was introduced in a commit on 2012-02-14, causing
character ranges to break due to bug that addition did not
commute for char + fixnum. Although the previous commit fixed
the regression, it's still good to have the object on the
left in case there are some future data types in case there
is ever some form of addition which does not commute.

Comment rewritten.
