How to invert direction of brackets (for a right to left text) in ConTeXt?

Question

The Unicode Bidirectional algorithm mandates that the glyph for the character "left parenthesis" (and many others) be inverted when displaying text in RTL direction.

However I am trying to typeset in ConTeXt a text in hebrew and parentheses appear incorrectly, )like this(. What can I do to invert them in the typesetting engine (I mean, without having to change the characters in the original text)? This question was asked before, but for LaTeX and XeLaTeX. I would need a solution for ConTeXt Mark IV

I attach a minimal working example:

\definefont[hebrewfont][arial at 12 pt]
\starttext
\textdir TRT
\hebrewfont
שלום (אני) כותב\\
\stoptext

Are you asking "Why doesn't this work as expected" or "How can I get it to typeset what I need, given how it works"? — einpoklum, Aug 30 '13 at 15:41
@einpoklum Good question, I'd like to know "how I can get it to typeset what I need, given how it works". — Ralph, Aug 30 '13 at 16:56
There are some examples for bidirectional typesetting at the end of typo-dir.mkiv. Btw. \enableregime is unnecessary and should be removed. — Philipp Gesang, Aug 30 '13 at 17:51

The proper, high level, commands for setting text direction in ConTeXt are \setupalign and \setupdirections (they are “experimental” though).

\definefont[hebrewfont][dejavusans at 12 pt]
\setupalign[r2l]
\setupdirections[bidi=global]
\starttext
\hebrewfont
שלום (אני) כותב\\
\stoptext

For my personal work I use the context-bidi module (wrote myself, even more experimental).

How do install the cotext-bidi module you mentioned above, when using Tex Live 2015 ? – Ibn Saeed Jan 18 '16 at 07:16
