Cool! But that won't help with lambda names leaking into template
instantiations' symbol via arguments unfortunately. So I think we really need
lambda names to be stable (which the PR does).

I was actually curious about the second issue: LDC seems to generate the code
for

alias f = () { ... }

for all modules that use `f`, while dmd only generates it if a module that uses
`f` is compiled together with the module that defines it (or if that's the same
module). Do you happen to know where does this difference come from?
