[NTG-context] Nested aligns in formulasjj

Hi,

I try to typeset a nested align in a formula. However, the results looks
really wrong. Here is a MWE:

```
\starttext
\startformula
	\startalign
		\NC a = \NC (b, c) \quad \text{with}\NR
		\NC   \NC \startalign
		            \NC b \NC = something \NR
		            \NC c \NC = someother \NR
		          \stopalign \NR
		\NC somelong = \NC bla \NR
	\stopalign
\stopformula
\stoptext
```
Am I doing something wrong or are nested aligns not possible?


Best,
Gerion

it will work if you configure the inner align to be tight (i delegate 
that answer)

\startformula
a               = \alignhere (b, c) \quad \text{with}
                   \breakhere b = \text{something}
                   \breakhere c = \text{someother}
                   \breakhere
\text{somelong} = \alignhere bla
\stopformula

might be okay for your purpose

Hi,

I do not understand what you want to have, so here is just something
weird, but probably you look for simplealign.

\definemathsimplealign
[whatever]

\starttext
\startformula
\startalign
\NC a = \NC (b, c) \quad \mtext{with}\NR
\NC \NC \startwhatever
\NC b \NC = something \NR
\NC c \NC = someother \NR
\stopwhatever \NR
\NC somelong = \NC bla \NR
\stopalign
\stopformula
\stoptext

Thanks, but unfortunately not. I guess, I simplified the MWE too much.
This does not align the b and c. It should become clear here:

```
\startformula
a               = \alignhere (b, thisislonger) \quad \text{with}
                   \breakhere b = \text{something}
                   \breakhere thisislonger = \text{someother}
                   \breakhere
\text{somelong} = \alignhere bla
\stopformula
```

Thanks, this looks exactly like that what I want. However, this does not
really nest aligns, but defines a new alignment group/environment (if I
interpret it correctly). But after all, it is a viable workaround.
