I do :-)  In fact, I use algebraic types supporting Null and 
Undefined for DTOs representation (and REST APIs).  But I 
discovered some "rare" side effects in libraries like vibe.d and 
structs where, sometimes, am empty string is deserialized as null 
(value is null) and I have to assume that null in an string is 
always "" for avoiding this weird effects

I'm under pressure to meet deadlines and a team that is telling 
me "Why D instead typescript, Antonio?"... One month ago I 
reported some questions in forums or git repos... but I have to 
finish my work and 2 hours stoppers are not acceptable now.

I will study it in detail and report (if required). May be, I 
will write the DTO problem with D article if I find time in 
august.
