TAP v12 spec[^1] shows the following as an example as TAP output that can be used to skip all tests with description​:

  1..0 # Skipped​: WWW​::Mechanize not installed

However, trying to run TAP​::Harness with such output crashes it with some failed internal typecheck​:

zoffix@​VirtualBox​:~/CPANPRC/Standard-Rakudo$ cat t.p6
say "1..0 # Skipped​: WWW​::Mechanize not installed"
zoffix@​VirtualBox​:~/CPANPRC/Standard-Rakudo$ ./perl6 -e 'use TAP; await TAP​::Harness.new.run("t.p6").waiter;'
Tried to get the result of a broken Promise

Original exception​:
  Type check failed in assignment to $!explanation; expected Str but got Any (Any)
