I find it a bit surprising that ConTeXt gives 'missing } inserted'
with:
\starttext\startformula
\mathop=^{\rm def}
\stopformula\stoptext
(\mathop{=}^... is fine, though).
The above formula is correct in Plain (Lua)TeX (in fact, it is
copied from The TeX Book). Why does ConTeXt need braces?
(Before you point it out: I know that I should use \stackrel…)

this is because \mathop is redefined (in th eprocess assuming a braced
argument) ... this is a mkii leftover which is actually no longer needed
(mkii needed more tweaks to get fonts right)
you can add this to cont-new.mkiv
\let\mathop\normalmathop
but i'd use { } anyway

don't worry ... i would not have thought of it (i never have to enter
that kind of math)
