This change shouldn't change the memory layout of hashmaps, because type synonyms get treated as if they've been expanded. If it does change the layout, that would be a pre-existing bug in the compiler. I agree unifying "%?" with I'll try to merge this. |

Oh, and happily, the refactor you did was independently made anyway by Patrick, to make the coherence checker happy (except the inner type is called |

Having trouble merging this. I think it might be a resolve bug. I'll look at it later on. |

Try to ensure measureme output is valid when the interpreter is interrupted Dropping our `measureme::Profiler` will have the profiler flush its output buffer and write out its string table. If the profiler's `Drop` impl does not run, the output file is not usable. This approach has zero runtime overhead.

Fixes #2566.
I had to do a bit of refactoring to make this work, because there is already a to_str instance for \forall T.@t, and hashmap has type @{...}, so I couldn't make a to_str instance for hashmap. Instead, I factored out the raw record type as "inner", and put the to_str instance on that. This required moving the private helper methods onto inner as well, which I guess works fine because of magical auto-dereferencing when calling them.
The thing I most worry about is that I have somehow changed the memory layout / behavior of hashmaps by doing this, but I don't think so.
There seems to be an aesthetic choice here between calling to_str on the keys and values, versus printing them with "%?". I chose the former as more consistent, but the latter produces slightly more useful output (printing strings quoted, e.g.) It seems like there should be a more unified notion of how to print things, somehow. Shouldn't "%?" be using the to_str iface, where present? Is there some iface it does use?
[Oh, and the actual printing code, which was the least trouble in this whole exercise, is stolen from the json module, which is why it uses a writer. I could do something else if it would be more idiomatic.]
