Objects of type string and logic_error will be created
for each assertion, even when ckecking is disabled.

Where efficiency counts, in a loop, this is absolutely
unacceptable.

     True enough. If templated it differently, and placed a req on the
     parameter to be string constructible, then could rearrange it thus:

        assertion<logic_error>(x ? t(3) : 3434==i+j, "must frobnicate
        before we tweak");
