I did it after restart of the Terminal, still ignores *

Worked after calling workspace() in the beginning. But it's too long

Are you using Windows? Have you checked out the master branch or are you on a release version? I believe this problem only occurs for windows users on Julia v0.6, it is fixed on Julia 0.7. There is no workaround for this, aside from doing something like * = Algebra.:*, unfortunately, due to an issue with how Julia 0.6 assigns the * operator only with WIndows on Julia 0.6 (not on julia 0.7).

Upstream issue: JuliaLang/julia#18769 and JuliaLang/julia#21540

The solution is to start using Julia 0.7, or to swtich to a different OS, because it can't be fixed for windows users on Julia 0.6 unfortunately, it's not a problem with my package, but the language.
