Yep, exactly what I needed.

Incidentally, while trying to see how its used I found that a lot 
of the links on the std.traits doc page do not work and have no 
documentation. For instance 
http://dlang.org/phobos/std_traits.html#isInstanceOf does not 
actually appear on the page but has a link to it up in the 
navigation header.

Other links on that page that don't work...
isAssignable, isBoolean, isIntegral, isFloatingPoint, isNumeric, 
isScalarType, isBasicType, isUnsigned, isSigned, isSomeChar, 
isSomeString, isNarrowString, isStaticArray, isDynamicArray, 
isArray, isAssociativeArray, isBuiltinType, isPointer, 
isAggregateType, isIterable, isMutable, isInstanceOf, unsigned

It seems that all the variable template's docs are not getting 
generated...
