variants of capitalization or spelling are not valid; they must be
converted to the format above. don't mimic the old atof behavior.
FWIW, that's not what I remember us discussing in the Perl 6 design
meeting (2009-01-28). In Perl 6 at least, "inf" is treated as infinity,
not zero.
In a larger sense, most groups seem to have accepted that "inf" and "nan"
conversions should be case-insensitive for parsing. Displaying the
mixed-case "Inf" and "NaN" on output is (afaik) a P6-only phenomenon,
most other languages seem to consistently do either "inf" or "INF"
(often by simply deferring to whatever atof does).
