I see, it is either the nuisance of having to type \& etc. in the text, or the nuisance of having to wrap everything like \halign in \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.
