evaln should not calculate anything,
only "-352.6" should become -352.6,
but "4+5" remains "4+5" and "3^2"
remains "3^2".
The intended purpose is a function
which extracts parameters a,b,c from a
string "a=7; b=John; c=-14.2", etc.,
without any further symbolic calculation.
Also "[3,2]" remains as it is, since it would
be seldom used.
Thanks
