@BruceEckel Thanks for reporting this issue. I believe it should already be resolved on coconut-develop, which you can get via pip install -U coconut-develop, however if you could verify that it works after you do that that would be appreciated.

If it still doesn't work after upgrading to coconut-develop, you should try using coconut --verbose, enter the same code, put the output on this issue, and I'll try to see what I can do.

Here's what happened with coconut-develop:

Then I tried coconut-develop --verbose and got this:

Then tried coconut --verbose and got what appears to be the same output (perhaps its the same command?)

@BruceEckel This should now be fixed on the latest coconut-develop; just pip install -U coconut-develop>=1.4.3-post_dev63 to get the fix.

When I ran that command a second time it seemed to work. Now the command just hangs:

>coconut-develop
Coconut Interpreter:
(enter 'exit()' or press Ctrl-D to end)
>>> range(1,10) |> reduce$(*, initializer = 1000) |> print


KeyboardInterrupt

@BruceEckel You should be able to safely ignore the first error you saw on pip installation. As for the second error, I can't seem to replicate it. Can you show me what happens if you run coconut-develop --verbose instead of just coconut-develop?

Also, fwiw, in case you're wondering what the correct syntax is for that command, you're looking for range(1,10) |> reduce$((*), initializer = 1000) |> print.

It just hangs.

When I tried your corrected syntax, I got:

@BruceEckel No idea why that's hanging for you—I'm running the same command on the same Coconut/Python/cPyparsing version and it gives a parse error as desired. Perhaps there's something wrong with your cPyparsing installation? You could try pip uninstall cPyparsing and then pip install -U coconut-develop cPyparsing. Alternatively, you could try just using pure Python pyparsing instead and run pip uninstall cPyparsing and pip install -U pyparsing.

As for the error with the corrected syntax, that error is exactly what should happen there, since reduce doesn't accept keyword arguments. You should be able to just do range(1,10) |> reduce$((*), ?, 1000) |> print instead, though.

It looks like a dependency may be overconstrained:

And the ? is what I've been hunting for. It's the equivalent of Kotlin's it, but I didn't know whether coconut supported it. Thanks!
