From @Juerd

It'd be nice if I didn't have to stringify this myself​:

  use lib $*PROGRAM.resolve.sibling('lib');

Currently, this results in the following failure​:

  Type check failed in binding to parameter '$spec'; expected Str but
  got IO​::Path

A simple workaround for now is​:

  use lib ~$*PROGRAM.resolve.sibling('lib');

I don't know if the right way involves supporting arguments of IO​::Path
explicitly, or to just coerce them to Str.

Thank you for the report. This is now fixed.

Fix​: rakudo/rakudo@3ff29d42f026fde
Test​: Raku/roast@0bed3721473fc472e

That's actually not a correct way to stringify paths if you wish the string
to refer to the same filesystem object​: https://docs.perl6.org/language/traps#IO::Path_Stringification
