Can't install anything past 0.5.5

[PMunch]

Trying to install a newer version of this package via Nimble just yields this error message:

Version 0.5.5 works

I cannot reproduce that locally (also 0.5.8 is the latest tag). But I'm running Nim devel. Can you check if it works on 2.0 or devel for you and/or if 0.5.8 works?

[PMunch]

Ah, turns out I had 1.6.14 checked out. With 2.0.0 I was able to install 0.5.8 (I tried 0.5.8 earlier as well, I just happened to copy the output for when I tried to install 0.5.7). The required Nim version in the nimble file should probably be bumped up to 2.0.0.

[Vindaar]

The required Nim version in the nimble file should probably be bumped up to 2.0.0.

I guess it's something that can be fixed. @c-blake is on vacation this week. I'm sure he'll have a look once he's back.

Sorry for the delay. As @Vindaar mentioned, I was out of town with only smart phone access where I find it almost impossible to do fast & furious source code edits.

Unfortunately, I could not get the New style concept matching (or {.explain.} to show why matching failed) working on older Nim's. So, I just forced an upgrade of the version.

This may sadly lock out people on older, frozen versions of Nim. On the plus side of the trade-off ledger, the core abstraction of an open-addressed hash table as just a specialized array with a few capabilities on array elements is more manifest with the adix/oats approach.

@PMunch - please let me know if this does not solve your problems.

Should work fine. Maybe drop a note somewhere that older versions of Nim must use 0.5.5 so people dont have to try every version. Other than that it should be fine.
