Hi Albert-Jan --
Maybe

[1] "slots" "contains" "virtual" "prototype" "validity"
[6] "access" "className" "package" "subclasses" "versionKey"
[11] "sealed"

[1] "logical" "numeric" "character"

[7] "expression" "list" "structure"
[10] "array" "matrix" "signature"
[13] "ObjectsWithPackage" "mts" "ordered"
[16] "namedList" "listOfMethods"
