<p dir="auto">Based on previous issues, it is not clear if there are plans to incorporate the implementation of <code class="notranslate">groupslices</code> from <code class="notranslate">GroupSlices.jl</code> into Base. This function is quite common when one needs to just find the <code class="notranslate">unique</code> columns in a large array for further processing.</p>
<p dir="auto">Past discussions include:</p>

<p dir="auto">The current registered version of <code class="notranslate">GroupSlices.jl</code> in Julia 1.x is a fork from the original author's version. Any chance this functionality could be part of Julia v1.5?</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="type Foo
end
bar{T&lt;:Foo}(x::T) = 1
methodswith(Foo)"><pre class="notranslate"><code class="notranslate">type Foo
end
bar{T&lt;:Foo}(x::T) = 1
methodswith(Foo)
</code></pre></div>
<p dir="auto">returns <code class="notranslate">0-element Array{Method,1}</code>, which doesn't seem right.</p>
