Prime - local recursive function definition

I think it is an error in Mathcad Prime 1.0 and 2.0 - see the picture

I've just been going through the process of updating my utility functions to try and make them work in both M15 and Prime 3.1.  Whilst converting a number of my worksheets I spent a good few minute painfully editing some functions to get them to work.   I'd forgotten about this particular problem, which turned out to be the source of my particular problems this time as well.   Rewriting these functions will be a pain, plus they lose the natural elegance of the recursive definition. 

I hope this 3 year old bug is in the pipeline to be fixed in Prime 4.0, along with restoration of currying (partial function application), the ability to pass a range definition as an argument to a function (eg, f(2..5)), re-definable global definitions and Math Styles (or equivalent) ... the lack of these capabilities is proving somewhat irritating.

It would be helpful if the Prime Converter:

converted an equation as best it could rather than, or in addition to, replacing it with an image of a non-convertible region.

extended a variable name with a Math Style name  (eg, func_MSU5 for function func defined in Math Style User 5) rather than convert to Variable ... this requires more attention to detail and effort than I'd like to manually separate converted functions with the same lexical name but differing Math Styles.
