Hello!

Could you please help me with this error message that happened when I installed Math::Matrix?

my bad, I know the source and will be fixed soon, as soon you see here version bump you will know its fixed

[lichtkind]

thanks for your trust but i will close issue when its actually fixed

Found again this error, with Raku 2019.11

Well, I have been trying to debug this, and it really beats me. It's really creating Rats, which are immutable, but the container (an array) shouldn't be. Somewhere along the line it's being itemized, or who knows, because normal Rats in normal (2-d) arrays can be smashed by any other value. So I don't really know. Might be a bug, but again, beats me.

[lichtkind]

sorry for late reply yes i know the source, wasnt that well last days i will fix it

[JJ]

@lichtkind there's a PR that fixes it also.

[lichtkind]
