I'm suggesting, I'm not likely to use it, and developing a D-specific
package manager should not accidentally exclude stand-alone building
of packages. As I said before, the build-system and packaging system

Just a thought; I guess the references to the non-GC-scanned strings
are held in GC-scanned memory, right? Are the number of such
references also increased linearly?
I'm not a GC-expert, but if so, wouldn't that pretty much force the GC

To be honest, while the only obvious benefit is shorting down the number of
braces slightly, the real benefit I experienced from practicing it in Ruby were
a slight change in how I actually think about exception handling.
