how is sort ordering specified?
Currently it is not specified, it defaults to infix:<cmp>. If you
can suggest a non-confusing way to specify both a transformation
closure and a comparison method, please go ahead.
how does it know to do string vs numeric sorting?
infix:<cmp> does numeric comparison if both operands are numbers,
and string comparison otherwise.
"Cmp" (like "eqv") depends on the particular type, so to sort a
certain way, you should need only to coerce the values to the right
type:
@stuff.sort { .Num } # numerically
@stuff.sort { ~ .name.uc } # stringwise
@stuff.sort { Foo(%x{$_}) } # foo-wise
I don't know what cmp returns for two values of different types.
