[REBOL] I hate computers!

No, really! I do.
Well, OK, when they don't do what I want, I hate 'em. :)
This is driving me nuts. I whipped up a small routine to validate
parameters. It is relatively simple, You pass it the parameter, you pass
it a series full of datatypes, it compares the two and tells you if your
parameter's datatype is valid (IOW, in the series).
But it's actin' strangely.
Here it is:
======================================================================
REBOL []
Valid-Type?: Func [ Parameter [Any-Type!]
DataTypes [Series!]
] [
ForEach DataType DataTypes [
If (Type? Parameter) = DataType [
Return True
]
]
Return False
]
======================================================================
The problem is in the line "If (Type? Parameter) = DataType" it just
doesn't work. When I call the routine, it does this:
>> Valid-Type? "x" [ String! Money! Integer! ]
== false
Which is incorrect. It should be "true" since "x" is clearly a string.
The only way it works, is when I change the line in question to "If
(join (to-string Type? Parameter) "!") = (to-string DataType)", which is
a little counter-intuitive.
So, bug or oversight? And is there, as always, a more elegant way of
doing this?
