named parameters for functions with defaults

[Răzvan Rotaru]

Hi,

I am seeking a way to have named parameters with default values in yeti. Intuitively, structures are good for that:

> myfun {a,b} = a+b
myfun is {.a is number, .b is number} -> number = <code$myfun>
> myfun {a=10,b=11}
21 is number

But how can I have default values for those parameters?
