I see, it is either the nuisance of having to type \& etc. in the text,

\unprotect..\protect and then resorting to \& again.
At least there is nothing amiss with \halign itself, which is
reassuring. However, I do not feel secure with these little deviations
from the orginal TeX.
orinal tex permits to set the catcodes so you need to define 'original tex'
anyhow, you can use \aligntab and \alignhash which wee introduced in
luatex for this purpose
which reminds me that one of these days on the context dev list we
should discuss this one
\catcode`€=\mathshiftcatcode
\starttext
€e=mc^2€
\stoptext
for typesetting math with continental style presets.
