This particular slowdown happens because there are somehow depdencies

Which has a ton of dependencies itself.
Aha! That explains it. Thanks, Stefan, for the accurate diagnosis. :-)
Now the next problem is: how to trim the fat off std.format ...
no wai. it is just Too General to be slim. what can be done, though, is
`std.format.lite` module (or something), that supports only a very small
subset of "big format" features, like simply printing numbers, arrays, and
unconditionally calling `.toString` on structs/classes, and a very
restricted set of formatting options. that should cover alot of use cases.
'cause most of the time people only need something like `%3d %s` and such.
