“Use of uninitialized value of type Any in string context.”

[AlexDaniel]

Sometimes I get this:

Use of uninitialized value of type Any in string context.
Methods .^name, .perl, .gist, or .say can be used to stringify it to something meaningful.
  in sub run-bisect at /home/alex/.rakudobrew/moar-master/install/share/perl6/site/sources/DB1CCAD0BA23019C934DC87B4C36FC5D82AC400C (Whateverable::Bisection) line 72

I don't think it affects anything, but it'd be nice to figure out what's going on there.

I would say it's the same intermittent error we're getting on the doc tests from time to time. It seems to appear when you're precompiling lots of files in a concurrent context...

I don't think. The line number points to sub run-bisect so there's probably some small bug in there.
