In addition to this usage, one can use {} for tensor-component notation:

\setupbodyfont[xits,10pt]

\setupmathematics[integral=nolimits]

The Ricci tensor
\startformula\relax
   R^i{}_{ikj}
\stopformula


There might be module or page for tensor component notation, if somebody would 
request it:

There is a standard ISO 8-2 [1-2] for natural sciences and technology, but 
not for pure math then, which I recall call for tensors expanded into 
components to be typed in sans-serif. In pure math, one is using serifs as 
always, with some other differences, usually sticking to a mathematically 
complete description with summation signs and basis.

In the Xcode text editor, one can show invisibles, but it does not tell which 
one, just showing a diamond, except for the NO-BREAK SPACE U+00A0, shown just 
as a space. In the mono-space font they are equal. If switching to the STIX 
fonts, suitable for math, then there is no THIN SPACE U+2009, so the editor 
switches to Lucida, in which it is nearly as wide as the no-break space.

Otherwise, this editor has good Unicode support. So \, and \! will prevail, 
though it might be nice to have visually less intrusive commands.

One should add
  \def\∫{∫}
before the code above. This way one can use both. For example:

\setupbodyfont[xits,10pt]

\def\∫{∫}

\appendtoks
\catcode`∫=\activecatcode
\letcharcode `∫ \int
\to \everymathematics

\setupmathematics[integral=nolimits]

Nolimits $\int_0^∞ f ω$, and $∫_0^∞ f ω$, and $\∫_0^∞ f ω$.

\startformula\relax
   ∫_0^∞ f ω, \quad \∫_0^∞ f ω, \quad \int_0^∞ f ω
\stopformula

A good example, illustrating a difference between \relax and {}, whatever it 
may be. I used it just to save some typing in a workaround. It must start with 
an integral sign having at least one limit:
\startformula   ∫_a f φ\stopformula
\startformula{} ∫_a f φ\stopformula
\startformula\, ∫_a f φ\stopformula
\startformula\relax ∫_a f φ\stopformula

Without limits, I get too much space after the integral sign:

I installed it on OS X 10.11.5 Beta in /Applications/ConTeXt. Then it turns out 
that adding ‘context’ to the PATH by a script
  exec /Applications/ConTeXt/tex/texmf-osx-64/bin/context "$@“
isn’t enough, because it gets hold of the older LuaTeX version from TeX Live 
2015 which is also in the path. However, running ‘setuptex’ works.

One can download a LilyPond binary to /Applications/, and its binaries then has 
lookup paths set properly to itself. Then scripts as those above have the 
advantage of not interfering with other binaries with the same name.

Also long spacing after the integral sign if there are no limits.

Currently, there is a problem with the lack of efficient Unicode input methods: 
symbol table and copy-paste are slow. But perhaps in the future, more might 
want to use it.

There may not be so many symbols: the “large operators" in the Tex Book, p. 
435, though Unicode have more, and some others like √ U+221A for \sqrt.

I could not make your code working - does it require a later LuaTex version 
(than 0.80.0)?

turn on

and making all those characters active by default is not a good idea


The use in the source code helps readability of math formulas, though.


it's no problem to make a module that supports that but it will never be 
default (some \mathcommand's represent base characters then become 
larger for instance while the corresponding base character is fixed in 
size), so ∫ by default is the character and not the 'adapting construct' 
(tex often has many commands for the same symbol doing different things)

The use in the source code helps readability of math formulas, though.
