UDO default parameters

[NicoLaval]

Issue Description

Considering the following UDO

define operator my_func (p1 string default "p1", p2 string default "p2", p3 string default "p3", p4 string default "p4", p5 string default "p5", p6 string default "p6", p7 string default "p7", p8 string default "p8", p9 string default "p9", p10 string default "p10")
returns dataset is
...
end operator;

Instantiate it overriding the 8th parameter only, has to be:

my_func(_,_,_,_,_,_,_,"P8", "P999")

It's not very pretty, and a source of error.

Proposed Solution

Enable to instantiate functions with positional parameters, named parameters, mix, like Python does.
It would be helpful:

my_func(p8="P8", p9="P999")

I would hope to never encounter am operator with 9 parameters, but I agree nevertheless

[NicoLaval]

I hope too but the example is in the abuse to demonstrate the concern

Agree
