Summary: M5: getTypeIndex && getTypeName misaligned?
Initial Comment:
b := bat.new(:str, :int);
t := inspect.getTypeIndex(b);
io.print(t);
s := inspect.getTypeName(t);
io.print(s);
returns:
[ 6 ]
[ "int" ]
(or is it that getTypeIndex doesn't work well on BATs?)

#Return the type index of a variable.
So, the implementation of getTypeIndex() does not match its
documentation.
Is there any other function/way in MAL to find out whether a variable is
of an atomic scalar type, or whether it is a BAT?

Clarification of semantics. It returns the typeindex of the tail type.
Upon need more will be added, e.g. (ht,tt):= getTypeIndex(b:bat[...
