Hi Hans,
Will |\mvert|and|\midalso be included in the \autofencelogic? It would be quite useful.|
i prototyped it but the chairman of the CMS has to check it before we decide to enable it one complication is that $ \autofences x | \frac{a}{x}$ $ \autofences ( \frac{a}{x} + b | x )$ should also work (lone middles)

I uploaded a new lmtx. Again some updated math of which details will be revealed later. Apart from some details we added suport for fourier notations. There are no high level definitions yet as we have to invent names but this is how it works (private unicode slots might change):
\setupbodyfont[pagella]
\starttext
\setupmathdelimited [topoffset=.2\exheight]
\definemathdelimited [fourier] [rule=no, left=\zerocount, right="FE944]
\definemathdelimited [courier] [rule=no, left=\zerocount, right="FE946]
\definemathdelimited [xourier] [rule=no, left=\zerocount, right="FE948]
$ \fourier{(z+1)} $
$ \fourier{(z+1)} + \sqrt[2]{1}$
$ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $
$ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + \xourier{\left(z+\frac12\right)} $
$ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + \xourier{(z+\frac12)} $
$ \widehat{x^2 + 2x + 2} $
\stoptext
This example also shows a new \autofences feature and widehats (widetilde and widecheck also work that way) that overcome limitations in fonts, so
\def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + #1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par} \CrappyHack\widehat \CrappyHack\widetilde \CrappyHack\wideacute \CrappyHack\widecheck
will work. For thise in finance we now have
$ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 1} $
these are basically radicals (like sqrt) with two sided symbols.
