*Very* interesting! May I ask which tool(s) you used to profile? Visual Studio's built-in profiler? (If any)

@cmeeren @jystic FYI, I've requested an open-source license from ReSharper which might help in profiling.

I'm also curious to find out what happens after trying what @Porges suggests [here](https://github.com/hedgehogqa/fsharp-hedgehog/issues/135#issuecomment-342048727): >I suspect that one nice win would be to replace `LazyList` with a `seq`, as long...

We can easily replace `UndefinedException` with something else as we're not explicitly relying on anything except FSharp.Core and the BCL. FSharp.Collections is referenced as a [source file](https://github.com/hedgehogqa/fsharp-hedgehog/blob/aa03bb9cad89360d20f1eab7d03a4137f5d1b67f/paket.dependencies#L20) and searching for...

If we remove BigInteger, what should we use instead? I have a feeling that this particular perf hit comes from [the handful of ad-hoc polymorphic things we need from FsControl](https://github.com/hedgehogqa/fsharp-hedgehog/blob/aa03bb9cad89360d20f1eab7d03a4137f5d1b67f/src/Hedgehog/Numeric.fs)...

These files are [fetched by Paket](https://github.com/hedgehogqa/fsharp-hedgehog/blob/aa03bb9cad89360d20f1eab7d03a4137f5d1b67f/paket.dependencies#L20-L22) directly from the FSharpx.Collections repo on GitHub. If we should edit them, then we should get rid of [these 3 lines in `paket.dependencies`](https://github.com/hedgehogqa/fsharp-hedgehog/blob/aa03bb9cad89360d20f1eab7d03a4137f5d1b67f/paket.dependencies#L20-L22) and...
