Ranges with large Num end points still let .int-bounds to succeed, because
the .floor == $_ (or .Int == $_) check checks out. The real Int number,
however, has noise in it:
<Zoffix_> m: say (1e100..1e200).int-bounds

This creates problems such as naive code like this successfully returns a sum.
It's a very noisy sum and isn't what a user[^1] expected:
<Zoffix_> m: say [+] 1..1e100

I dunno, is the floating point noise something the user should be familiar with
or should we somehow go extra length to prevent such cases and error out or
something?
