\eqaligno crashed

\eqaligno crashed

[Meer, H. van der]

Now \eqaligno crashes. Please, can this be repaired. It is so common a macro that I cannot complete my work without.

Minimal example:
\starttext
\placeformula\startformula
\eqalignno{
	x &= j\cr
	x &= j\cr
	}
\stopformula
\stoptext

! Undefined control sequence.

\eqalignno ->\math_both_eqalign_no_normal 
                                          \math_prepare_r_eqalign_no 
l.3 \eqalignno

BTW: ConTeXt has it’s own align/matrix etc. environments for math since a long time.

\starttext

\startformula
\startalign
\NC x \EQ j \NR
\NC x \EQ j \NR
\stopalign
\stopformula

\stoptext

Why not just use \startalign etc.
