Can't match type predicates in Python

[morgante]

The $type condition doesn't work here.

engine marzano(0.1)
language python

`def matching_method($_) -> $type:
  $body` where {
    $type <: `List`
  }

Note this also doesn't work:

type() as $t where {
    $t <: `List`
}

Easy enough to work around though: Note this also doesn't work:

type() as $t where {
    $t <: contains `List`
}
