[nem-en] default parameter value

[Kamil Skalski]

Hm... wait a moment - I can see following code in parser:

          mods.custom_attrs = <[
System.ComponentModel.DefaultValueAttribute ($e)
                              ]> :: mods.custom_attrs;

So maybe come back to the original question and try
System.ComponentModel.DefaultValueAttribute attribute... :)

And here I can see there is a collision of having ..$attrs   and   =
$default at the same time.
