[Haskell-cafe] Proposal: Shorter Import Syntax

Here are some more numbers. In our private code base of ~12,400 modules totalling >2,300,000 LoC, there are ~143,800 import lines, of which ~65,000 use the "as" syntax. Of those, ~8,000 have no "qualified", and the remaining ~57,000 use "qualified". So I make that about 5.6% of our imports. I think this is quite a lot higher than the Stackage figure, because this code is mostly applications rather than libraries, so it tends to use a larger range of imported functionality from lots of different semi-independent domains. The chance of naming-overlap for separate concepts is therefore much greater, leading to our common idiom for optional qualification of names with short module synonyms (often single letters).

I grepped through the source of all the packages in the Stackage Nightly
package set and found that less 0.3% of imports use that syntax. It's
a small number, but it's not zero, so the breakage would be
