While I can accept that some users will find it useful to enter
equations in a format similar to fortran/C/matlab, I don't think that
providing such a facility should take up any more resources than
necessary. My feeling is that time might be better spent using one
(or more) of the established language syntaxes. This (these) could
then be transformed using a simple XSLT (or similar) into Content
MathML. In this way we avoid stuffing around inventing yet another
syntax - something I really, really don't think is worth the effort.
It also will provide some of the tools required for automatic
translation between common languages and Content MathML. Issues about
automatic reordering of equations are way down the hierarchy of
importance. In this area, I feel that the translator should reflect
directly the input of the user. There may well be sound numerical
reasons why an author might wish to impose a specific order of
evaluation (e.g. to avoid numerical problems due to cancellation), as
well as user interface issues (least surprise to the user).

Best wishes
Poul
