From @AlexDaniel

Code​:
my $i = 'a'.Int

Result (2015.12, 2016.03)​:
Cannot convert string to number​: base-10 number must begin with valid digits or '.' in '⏏a' (indicated by ⏏)
  in block <unit> at /tmp/2R0qtbz9ME line 1

Actually thrown at​:
  in block <unit> at /tmp/2R0qtbz9ME line 1
«exit code = 1»

Result (HEAD)​:
(Failure)

So instead of throwing it just gives a Failure object.

Bisectable points to rakudo/rakudo@1cb2e8d

I find the current behavior a bit surprising, but feel free to argue with that.

From @lizmat

To me, that’s ENOTABUG, because that’s exactly what fail / Failure is supposed to do. Only when you actually *use* the value unprotected, will it throw.

# protected usage
$ 6 'my $i = "a".Int; say $i // 42’
42

# unprotected usage
$ 6 'my $i = "a".Int; say $i'
Cannot convert string to number​: base-10 number must begin with valid digits or '.' in '⏏a' (indicated by ⏏)

The commit fixes behaviour.

From @AlexDaniel

You are right. This is not a regression, but we still need some tests for this I think.
