If I get it correctly, the following two formulae should render differently - and they don't. What is going on?

\setupmathematics[autopunctuation=yes]

\starttext

$(2,5)$ versus $(2, 5)$

\stoptext

Spaces in math mode are ignored because the spacing is controlled by different rules.

\starttext

\m{1.2}\par \m{1. 2}\par \m{1 .2}\par \m{1 . 2}\par

\blank

\m{1,2}

\blank

\setupmathematics[autopunctuation=yes]\m{1,2}

I always thought that autopunctuation was targetted towards the European tradition of using comma as a decimal separator. That behavior can be achieved by changing a comma to be an "ord" from a "punctuation". However, changing the comma to an "ord" has the drawback that you have to explicitly add spaces when comma is needed as a punctuation, for example in sets: \m{A = \{a,\, b,\, c\}} Autopunctuation is supposed to get around this: if comma is followed by a non-space, the comma should behave like an "ord"; if it is followed by a space, it should behave like a "punctuation". Clearly that is not happening. Aditya
