_kind
What kind of Thing is this? --
Function
There are two ways to use _kind:
THING -> _kind -> Number
This function produces the Number that represents the "kind"
of the received Thing. The Kinds are:
- Thing: 0
- Type: 1
- Property: 2
- Space: 3
- Collection: 4
By and large, though, you should never use these numbers directly. Instead, use
the second form of this method:
_kind(KIND) -> Number
The KIND parameter should be exactly one of the above names.
So for example, you can test whether the incoming Thing is a Property by saying:
... -> if(equals(_kind, _kind(Property)), ...)
