Hi all,

doing some tests I discovered two interesting facts.

The first is that commands \starttext and \stoptext do not behave as a grou= p.

Minimal example (tested on TL2015, TL2016, TL2017, current CTX from the Gar= den):

\starttext
text
\starttext
\bf text
\stoptext
text % this text is in bold, too.
\stoptext

Is this the expected behaviour, or not?

Opening a group with \starttext makes no sense because there is nothing aft= er \stoptext.

The possibility to nest \starttext is necessary when you \startproduct etc.= where components
can be be documents on its own and this means \startcomponent includes \sta= rttext in its
definition.
 
The second interesting thing is that the unbalanced document is compil= ed without protests:

Minimal example #1 (tested on TL2015, TL2016, TL2017, current CTX from the = Garden):

\starttext
text % in this case, the "text" is shipped out

Take a look at the command line when you process a file and you should see = something like this:

mtx-context     | run 1: luatex --fmt=3D"[...]/con= t-en" --jobname=3D"test" [...] --c:input=3D"./test.tex&= quot; [...] "cont-yes.mkiv"


As you can see the luatex engine processes the file cont-yes.mkiv and not y= our document
which put as argument to context. Your document is just read by cont-yes.mk= iv and at the
end of the document ConTeXt inserts an extra \stoptext which is ignored whe= n your document
is valid (equal number of \starttext and \stoptext).
 
Minimal example #2 (tested on TL2015, TL2016, TL2017, current CTX from= the Garden):

text % in this case, the "text" is not shipped out
\stoptext

The reason why no text appears is that ConTeXt doesn’t load the defau= lt fonts
untill \starttext. The reason for this is to is a gain in speed and you sav= e resources.

You can test this by adding \setupbodyfont[modern] at the begin of your exa= mple.
