(s)printf misleading error message should report values, not types

[Altreus]

printf should report the value when it could not be applied to a directive; currently, it reports the type of the value.

> printf("%d",Inf)   
Directive d not applicable for type Num

This is misleading when the type is expected to work, but can have unworkable values; in the above example, it is surprising to hear that Num does not apply to d, whereas in fact it is Inf or NaN that don't apply to d.

Another misleading case is Str, since again it is the value that is unusable, not the type:

> printf("%d", "1")
1

> printf("%d", "raku")
Directive d not applicable for type Str

Thanks for the report. This is now fixed!
