Leancheck looks great! Could you also please compare it to feat? That's what I've been using for enumerating algebraic datatypes by size (vs depth) so far. <br><br><div class="gmail_quote"><div dir="ltr">On Fri, Jan 18, 2019, 16:22 Joachim Breitner <<a href="mailto:mail@joachim-breitner.de">mail@joachim-breitner.de</a> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>

Let’s hope we get Haskell2x somewhen, including (at least)<br>
PatternSignatures, or even all of ScopedTypeVariables.<br>

Interestingly, my proposal cites a rant from you from 10 years ago:<br>
