(In reply to comment #17)
I have suggested to introduce the "..." syntax for arrays just because Walter
thinks global arrays are often initialized partially. Some evidence shows this
is a really uncommon need, so maybe it doesn't deserve a special syntax and it
doesn't deserve to leave a trap in D that's a confirmed (by Don too) source of
bugs. Don also has suggested a library solution that maybe makes "..." useless
or less needed.

The first and main purpose of the "..." syntax is to denote a global/static
fixed-sized array that is underspecified (and all items not specified default
You propose to add a secondary purpose to the "..." syntax, that allows to
specify what's the value of all the not specified items, to ask for a value
different from T.init. I have seen not even one use case for this sub-feature,
this is bad for this idea.
I my note about engineers I have tried to explain that engineers often have
aversion of designs that conflate two different purposes into a single "user
interface", especially if one of the purposes isn't a confirmed need and if it
creates problems when it's used alongside other features (floating point
numbers without leading digits). So I fear that the appreciation of Walter of
this idea is _decreased_ by the idea of adding this sub-feature.
