The whole point of UFCS is to be able to provide additional
custom "methods" to a object (class or struct). Constructor
UFCS don't fulfill that use case.
Nothing is removed from the language as factories method can be
introduced anyway.
This frames the topic in a wrong way. Constructors are not normal
functions, they are special, but functional languages show us
that's it's a very good idea to see them as functions.
And the original point of UFCS doesn't matter much. What matters
is what are the practical disadvantages of allowing UFCSyntax for
constructors (like the original post in this thread), and what
are their practical advantages/uses (like a handy usage in UFCS
chains). Then we take a look at what's the resulting balance and
we decide. And such decisions should then become the written
specifics of this part of the D design.
