As an abstract exercise, if we were allowed to implement DSL, what would it look like? Here's an (original?) idea: to write the structure of the widget in a manner...

Variant: instead of "default", use "pass" or "nop" or "noop"

Yes, I was thinking about "void" too :) It's a good word indeed, I was afraid it can cause some parsing conflicts with another meaning as a data type, but...

There's another concern that new type of "if" will be made redundant if argument block is implemented. Argument block is a very promising idea, it adds a lot of power...

if you add spread operator, then the language doesn't gain much from "if" element, because then you can always write ``` var extraParams = condition? { named: argument, another: argument...

Map may be retrofitted with a constructor with vararg list of MapEntries: `Map.fromEntries(MapEntry entries...)` Then it will be possible to write (see the discussion in #15) ``` var map =...

Late variables are evaluated lazily, so the presence of default value won't prohibit the use of `?? a` - unless the variable was accessed before the test: ```dart f({late x=1,...
