Error related to removing !any (false positive)

The following should not pass:

Something <- Sim*ple
a_class <- [a-p]

Currently it is parsing without an error but only returning part of the AST:

["Grammar", [
  ["CheckDef", [
    ["CheckId", "Something"],
    ["Expression", [
      ["Sequence", [
        ["Plain", [
          ["CheckId", "Sim"],
          ["MinZero", "*"]
        ]]
      ]]
    ]]
  ]]
]]
