Considering there are already many concerns about complexity introduced by
generics, the situation will be even worse when generics arrive without
eliminating the built-in magic stuff. Then is generics really worth the
trade-offs? Does the gain outweigh the pain?

Even if it were possible to eliminate the built in generic stuff, I think
it would be a bad idea to do so.
For better or for worse it's now part of the fabric of the language and
just about every program ever written in Go 1 would have to be fixed if it
were replaced.
Also there are many in

Although I've relied on compiler magic for my previous proposals, I believe
we should keep it to a minimum if we can, The 'union' and 'except' idea
would allow us to compose any group of types we want from the basic

Hi,

Hi Ian,
Thank you for your post.
Those overhead you mentioned come from goroutine scheduler for entering a
system call.
Apparently, there is no such mechanism in Go to submit an IO "transaction"
if there are two

I think your idea of creating standard contracts to represent similar types
is a good one. However, you don't have to say how those contracts are
written, just what they do. No need for typecheck, union, except, etc. For
example,
Integer(T) - T is an integer type
Float(T) - T is a floating point

When using 'go mod vendor' why are there lots of files missing? I'm

mismatches in the vendor folder structure.
Does this command only vendor the actual files used for compilation?
Because a lot of tests and examples are
Your stack trace isn't long enough to see the usage of ipfs leading up to

Somewhere in there you must have a nil pointer to a RequestBuilder, on
which Send() is being called.

You don't need the io.Pipe: it's fairly trivial to implement io.Reader in

You can even implement io.WriterTo efficiently that way:

Small, but important, correction re #5:
5. Any contract could contain at most one 'union' or 'except' assertion *for

Jonathan,
The problem with just 'OR'ing complex64 and complex128 together is that the
resulting contract wouldn't encompass any defined types with the same
underlying types. So 'mycomplex' wouldn't be included:
type mycomplex complex64
However, I'm pleased you mentioned it as it's given
Hi John,
When using a replace target that is a local filepath, yes, the target
does need to be a module (this is in effect simulated by the go tool
when a "module" is fetched from a remote VCS in case a project is not
a module).
That's fixed in the most simple cases by creating a go.mod file in
Perhaps just for completeness here, the replace directive is almost
certainly what you want when it comes to unpublished modules. This
will allow you to refer to a remote module as if it were published,
even though it resides on a local disk.
