Thank you! I opened the trace of my project in chrome://tracing 
and found that the majority of semantic analysis was spent on 
instantiations of `std.conv: text`. I replaced them and 
compilation time went down from 2.1 to 1.6 seconds, which I think 
is a big win!

I'm already happy with what is there, but so far the most 
annoying part is that chrome's viewer is terribly slow and 
unresponsive. It can easily take a minute to load a trace, after 
which it runs at 1 frame per second, so I'm looking for an 
alternative.

The article mentions Speedscope, but my first impression isn't 
that great: it's still slow, and the interface is not 
self-explanatory unlike Chrome's.

In the PR you mentioned tracy*, but I'm still looking at how to 
compile it for Linux since the release only seems to include 
Windows binaries. I guess I'll try it out on Windows first.
