[perl #125293] Match objects don't roundtrip through .perl

[Christian Bartolomaeus via RT]

As far as I understand it, the problem can be golfed to the following:

$ perl6 -e 'say EnumMap.new("a", 42).perl'
EnumMap.new(:a(42))

$ perl6 -e 'say EnumMap.new("a", 42).perl.perl'
"EnumMap.new(:a(42))"

$ perl6 -e 'say EnumMap.new("a", 42).perl.EVAL'
EnumMap.new()
