I wanted to use this argument for an easy specification of, well, a title for a "recipe". The advantage is that all information is held together and it's easy to use for people who are not (too) familiar with ConTeXt.

context has no (need for) \long ... all is long (i mever saw a reason
for using it)
(1) use a proper head:
\definehead[RecipeHead][subsubsubsubsubsubject]
\setuphead [RecipeHead][style=bolditalic,after={\blank[medium]}]
\definetabulate[recipetab][|l|l|p|l|]
\setuptabulate
[recipetab]
[bodyfont=small,
distance=medium,
before={\blank[back, small]},
headstyle=bold,
headcolor=red]
here's a one-step lmtx solution:
\let\stoprecipe\relax
\tolerant\protected\def\startrecipe[#1]#*[#2]#3\stoprecipe
{\ifcstok{#1}\emptytoks\else
\RecipeHead{#1}
\fi
\ifcstok{#2}\emptytoks
\startrecipetab#3\stoprecipetab
\else
\startrecipetab[#2]#3\stoprecipetab
\fi}
or just
\tolerant\protected\def\startrecipe[#1]#*[#2]#3\stoprecipe
{\ifempty{#1}\else
\RecipeHead{#1}
\fi
\ifempty{#2}%
\startrecipetab#3\stoprecipetab
\else
\startrecipetab[#2]#3\stoprecipetab
\fi}
and here's one that does what you ask (in the core i'd try to avoid
grabbing too much arguments and if real core we'd make sure dummy
parameters don;t interfere):
\tolerant\protected\def\startrecipe[#1]#2\stoprecipe
{\ifempty{#1}%
\startrecipetab#2\stoprecipetab
\orelse\ifhastok={#1}%
\getdummyparameters[headtitle=,#1]
\ifempty{\dummyparameter{headtitle}}\else
\normalexpanded{\RecipeHead{\dummyparameter{headtitle}}}
\fi
\startrecipetab[#1]#2\stoprecipetab
\else
\RecipeHead{#1}
\startrecipetab#2\stoprecipetab
\fi}
\startrecipe[headtitle={Head 3},headcolor=blue] % pass on arguments to
tabulate
\FL
\BC Absolute \BC Stock \BC Ingredient \BC Final \NR
\HL
\NC 1 \NR
\LL
\stoprecipe
Here's a variant:
\def\theparameter#1#2%
{\beginlocalcontrol
\begingroup
\getdummyparameters[#1=,#2]%
\normalexpanded{\endgroup\endlocalcontrol\dummyparameter{#1}}}
\tolerant\protected\def\startrecipe[#1]#2\stoprecipe
{\ifempty{#1}%
\startrecipetab#2\stoprecipetab
\orelse\ifhastok={#1}%
\edef\MyHeadTitle{\theparameter{headtitle}{#1}}%
\ifempty\MyHeadTitle\else
\normalexpanded{\RecipeHead{\MyHeadTitle}}
\fi
\startrecipetab[#1]#2\stoprecipetab
\else
\RecipeHead{#1}
\startrecipetab#2\stoprecipetab
\fi}
or just
\tolerant\protected\def\startrecipe[#1]#2\stoprecipe
{\ifempty{#1}%
\startrecipetab#2\stoprecipetab
\else
\edef\MyHeadTitle{\theparameter{headtitle}{#1}}%
\ifempty\MyHeadTitle\else
\normalexpanded{\RecipeHead{\MyHeadTitle}}
\fi
\startrecipetab[#1]#2\stoprecipetab
\fi}
or
\tolerant\protected\def\startrecipe[#1]#2\stoprecipe
{\ifempty{#1}%
\startrecipetab#2\stoprecipetab
\else
\ifcstok{\theparameter{headtitle}{#1}}\emptytoks\else
\normalexpanded{\RecipeHead{\theparameter{headtitle}{#1}}}
\fi
\startrecipetab[#1]#2\stoprecipetab
\fi}
or ... or ... or ...
just play with it a bit till you have something that looks nice in code too
