Found it where you said:

method new(Proc:U:
         :$in = '-',
         :$out = '-',
         :$err = '-',
         Bool :$bin = False,
         Bool :$chomp = True,
         Bool :$merge = False,
         Str:D :$enc = 'UTF-8',
         Str:D :$nl = "\n",
     --> Proc:D)

What is .bin?  Binary?  Binary what?  Is somethings
returing binary?

What is .chomp?

What is $enc?  Encrypted?  How does that work?

Is .nl New Line?  And I presume that is the
returned text?  Does it conflict with .bin?
