on the length of symbols

[weaselcat via Digitalmars-d]

here's a single symbol from my project

that's 1,872 bytes.

but maybe it's just my project, I might have made some serious D
mistakes. I know, I'll check vibe.d

hm


compiling vibe.d generates 12 megabytes in symbols, ~75% of them
are completely unable to be demangled by current D demangling
tools.

But surely, phobos couldn't be this bad?

I'd put the symbol here, but it's too long and got rejected by 
the NG. So, you can view it here. https://paste.ee/r/cIuGm
