Thanks, Hans, for the answer, but I'm not sure if I get the point.
While this is possible in ConTeXt:
\startsection[title={My Title}]
\beginMyBlock bla bla \endMyBlock
\stopsection
The following won't work (end of file error):
\startMyCommand[optional={Maybe}]
\beginMyBlock bla bla \endMyBlock
\stopMyCommand
I had hoped for a simple command/modifier like \pleaseacceptblocks\def\startMyCommand[#1]#2\stopMyCommand to have #2 work in a similar way.
But maybe, as Wolfgang stated here (https://www.mail-archive.com/ntg-context@ntg.nl/msg73956.html), buffers and blocks can't be used in commands. (To add: Even when passed as arguments during compilation?)
You can bet that WS is right. You really have to go dirty tex for this kind of magic: \defineblock[MyBlock] \keepblocks[MyBlock] \starttext \tolerant\def\startMyCommand[#1]% {\begingroup \setcatcodetable\notcatcodes \dostartMyCommand[#1]} \let\stopMyCommand\relax \normalexpanded{\def\noexpand\dostartMyCommand[#1]#2\expandtoken\notcatcodes92 stopMyCommand}% {\endgroup % whatever #1 does \setbuffer[foo]#2\endbuffer \typebuffer[foo] \getbuffer[foo]} or \normalexpanded{\def\noexpand\dostartMyCommand[#1]#2\retokenized\notcatcodes {\stopMyCommand}}% {\endgroup % whatever #1 does \setbuffer[foo]#2\endbuffer \typebuffer[foo] \getbuffer[foo]} \startMyCommand[optional={Maybe}] \beginMyBlock bla bla \endMyBlock \stopMyCommand \stoptext and then of course further nesting mess ...
