`isa(Cpp.Node.Node node)`	Checks whether `node` is a `PreprocDef`.
`cast(Cpp.Node.Node node, required PreprocDef &cast)`	Finds `PreprocDef` nodes from `node` when compatible.
`name(PreprocDef self, Cpp.Node.Node &child)`	Matches the macro name being defined.
`value(PreprocDef self, Cpp.Node.Node &child)`	Matches the replacement value of the macro.
`isEnclosedInPreprocDef(Cpp.Node.Node child)`	Checks if `child` appears inside a `PreprocDef`.
