Str$(Type Variable) - Question

I am refering to the official command reference for TYPES:
A cunning trick for debug purposes, or for saving data from types to a file, is to use the Str$ command. Print Str$() will print the values of each field of the type in turn, comma separated, within square brackets, e.g. [15,42,"Fluffy",500].
THIS DOES NOT WORK in my application. The return value is always [OBJECT]. Can somebody help? Thanx.

This works with previous versions of Blitz, which is how it got in the command reference.

But it doesn't work in BlitzPlus. That's a shame because it was a neat little 'lazy programmer' time saver.

bummer dude

Actually, I believe it works in the B+ demo (v1.11) but not in the full version after you apply all the updates.
