Code​:
Nil.chrs

Result​:
Use of Nil in numeric context
  in block <unit> at -e line 1

At the same time​:

Code​:
Nil.ords

Result​:
Use of Nil in string context
  in block <unit> at -e line 1

I think that both should say that it is in string context.

chrs takes an array of Ints and returns a Str; it's trying to use Nil in a numeric context to get a number to work with.

ords takes a Str and returns an array of ints - it's trying to use Nil in a string context to get character to work with.

Seems fine. Rejecting ticket.

.chrs takes a list of numbers. The Nil is used in numeric context, resulting in a 0, which after being .chr'ed results in a null string​:

m​: quietly say Nil.chrs eq "\x[0]"; # True
rakudo-moar abc643​: OUTPUT«True␤»

The warning is accurate.
