IO​::Path.perl produces output of the general form
$a.IO(​:SPEC($b),​:CWD($c)), but it turns out that this expression doesn't
actually replicate the SPEC and CWD attributes​:

"foo".IO(​:SPEC(IO​::Spec​::Unix), :CWD("/bar")).perl
q|foo|.IO(​:SPEC(IO​::Spec​::Unix),​:CWD</home/zefram/usr/rakudo/rakudo>)
"foo".IO(​:SPEC(IO​::Spec​::Win32), :CWD("C​:\\bar")).perl
q|foo|.IO(​:SPEC(IO​::Spec​::Unix),​:CWD</home/zefram/usr/rakudo/rakudo>)

Empirically, it would work to instead generate a IO​::Path.new expression​:

IO​::Path.new("foo", :CWD("/bar")).perl
q|foo|.IO(​:SPEC(IO​::Spec​::Unix),​:CWD</bar>)
IO​::Path.new("foo", :SPEC(IO​::Spec​::Win32), :CWD("C​:\\bar")).perl
q|foo|.IO(​:SPEC(IO​::Spec​::Win32),​:CWD<C​:\\bar>)

This is distinct from the string quoting issues that arise in the same
code and are being addressed in [perl #​126935].

FWIW, I’m not ready to drop the .IO form, because we may want to be able to override that coercer in the future.

Thank you for the report. This was a month or so ago, as part of the IO grant.

Tests now exist in https://github.com/perl6/roast/blob/a5d933fcefd97ab15b2b2c3cefc8ec7e67a9179c/S32-io/io-path.t#L58-L91

Closing.
