UHT "Type TArray is not supported by blueprint" error message is ambiguous

An overly generic error message is produced when you have a TArray UProperty that contains a non-blueprint friendly type.

For example:
UPROPERTY(EditAnywhere, BlueprintReadWrite, editfixedsize)
TArray<FInputBlendPose> MyVariable;

would produce the following error message:

LogCompile: Error: Type 'TArray' is not supported by blueprint. MyClass.MyVariable

The true problem is that FInputBlendPose is not Blueprint friendly and conflicts with the BlueprintReadWrite markup on the TArray declaration.

Changing the error message to include template type arguments, such as either of the following error messages would be ideal:

LogCompile: Error: Type 'TArray<FInputBlendPose>' is not supported by blueprint. MyClass.MyVariable

LogCompile: Error: Template Type 'FInputBlendPose' in 'TArray<FInputBlendPose>' is not supported by blueprint. MyClass.MyVariable

Declare a blueprint friendly TArray of a non-blueprint friendly type such as

UPROPERTY(EditAnywhere, BlueprintReadWrite, editfixedsize)
TArray<FInputBlendPose> MyVariable;
