<div>Why do you need this additional check on MEM_Blob?</div>
<div>Is it possible that memory holds raw msgpack and its</div>
<div>type not blob? If so, please provide an example.</div>

I'm not sure what you describe is possible. But it is impossible<br>
to say what type MEM has when you look at the SUBTYPE. At the same<br>
time, the subtype has any meaning only for BLOBs. Any other type<br>
has any SUBTYPE, and it is not checked anywhere. So, to avoid an<br>
error, when something, for example INT, throws an error when<br>
casting to SCALAR, I added these checks.<br>
