Bug description

I really wish that the basic features of metaocaml, namely .< >., .~ and .! were included in OCaml proper. The many other experimental features of metaocaml could stay 'experimental', those are the 3 which are sorely needed.

Note that OCaml could be really ahead of Haskell here (with its untyped Template Haskell, which is closer to camlp4 than to metaocaml) by being the first production language to have typed metaprogramming facilities.

Yup would like to get it integrated in mainline ocaml too

It would be great if ocaml could incorporate basic metaprogramming!

I too would like to see this happen, and would be happy to help.

Good idea.
It would also respond to a request appeared in the OCaml Journal:
Metaprogramming with MetaOCaml (27th July 2008)

I support the proposal of making the basic meta-programming features of metaocaml part of OCaml

This would be a fantastic addition to ocaml!

I'd like to see these useful capabilities added to OCaml soon.

I've used PE techniques at the companies VLSI Libraries and Artisan Components
to great effect but I used them with Scheme. It would be great to be able to
use them with Ocaml. Not having the PE capability in a production release of
Ocaml prevents me from using MetaOcaml at work.

We'd be interested to use this in the investment bank where I work.

The metaprogramming constructs .< >., .~, .! are really
useful for type-safe run-time code generation and should
be made part of the standard OCaml distribution, to be sure
that they are available in all future versions of OCaml!

I would simply love that. I can think of plenty of problems which could be solved by such a feature, from boilerplate stuff to optimizations. More than that: I can well see myself using this.

I think it would be great having typed metaprogramming into the standard OCaml distribution.

I think this would be great thing to have in the core distribution. It seems that as a feature it overlaps with camlp4 to a large extent, so it would be nice to see these brought more closely together into a unified meta/macro extension.

I've never been thrilled with the syntax chosen for metaocaml though. [|...|] would be a much more natural for quasi-quoting since this what all the academic papers use, although unfortunately it's already in use for arrays. (FWIW, I would probably use metaocaml features much more often than arrays!)

Discussion about incorporating parts of MetaOCaml comes up fairly regularly, but given there have been no specific patches proposed here, I think this old issue is redundant. When and if those responsible for MetaOCaml (or others) would like to pursue further the question of integration we will be pleased to receive patches and discussion via Github as is now usual. That will give a substantive basis on which to proceed.
