Has anyone given thought to how an SV can contain both a numeric value
and string value in Perl6?
Given the arbitrary number of numeric and string types that the vatble
scheme of Perl6 support it will be unviable to to have special types
for all permuations (eg, utf8_nv, unicode32_iv,

3. We decree that all string to numeric conversions should return
a particular numeric type (eg NV), and that all numeric to string
conversions should similary convert to a fixed string type (eg utf8).
(Although I'm not sure that really helps.)
Feels like a bad plan, as it can be that

more a perl5 question - why IV not int?
int might be smaller and "more natural" (your words)
eg why does looks_like_number return IV not int? and various other bits
of the perl API use IV?

Well just the 1st time - then it is a number...
Err, option (1) was explicity suggesting we *dont*
It seems to me the following options are poossible:

$i="3"; $j+=$i for (...);

I fear this would be a performance hit. I'm told TCL pre version 8 was
like this - everything's a string and

Hmm, you may be right at the level of your example, which may indeed
be typical of pp_(). Perhaps PerlIO is so bother some
