math, displaymath environments

[cben]

LaTeX supports \begin{math}...\end{math} and \begin{displaymath}...\end{displaymath}; in fact $...$, \[...\] etc. are just shorthands for these environments. Could MathJax support these? Currently they produce an error, whether used inside math delimiters or outside.

[Why do I care (aside from latex compatibility on general principles)? In the context of math in markdown, I'm sceptical there can be concensus on delimiters and want some common-denominator syntax that could work "everywhere", irrespective of shorthand delimiters of implementor's choice — even if annoyingly verbose. I suddenly rememebered LaTeX has environments for inline & display math :-), only to discover MJ doesn't support them :-(]

Sounds reasonable enough to me.

Still actual. The VNote and ReText can't render the equation below (both use MathJax):

\begin{displaymath}
    \lim_{n \to \infty} 
    \sum_{k=1}^n \frac{1}{k^2} 
    = \frac{\pi^2}{6}
\end{displaymath}

but Pandoc-based applications show it as expected:
