[NTG-context] Characters allowed in macro names

I was wondering if it is alright to use underscores in the names of
macros, e.g, as in the following file.  It looks like \startsetups, and
\def accept names with hyphens, underscores, and numerals, but
\starttexdefinition doesn't tolerate any of them.

1. In general, what characters are allowed in macro names?  Are Unicode
   characters admissible?

2. Apart from the fact that one can use whitespace freely in
   \starttexdefinition, is there any reason to prefer it over \def?

Thanks,
Raghu.

\starttext

\startsetups [hello-world_1]
  Hello, world 1!
\stopsetups

\setups [hello-world_1]

\def\hello-world_2{Hello, world 2!}

\hello-world_2

\starttexdefinition helloWorld
  Hello, world!
\stoptexdefinition

\helloWorld

%% Doesn't work
%% \starttexdefinition fooBar1
%%   Foo, bar 1!
%% \stoptexdefinition
%%
%% \fooBar1

%% Doesn't work
%% \starttexdefinition foo_bar
%%   Foo, bar!
%% \stoptexdefinition
%%
%% \foo_bar

%% Doesn't work
%% \starttexdefinition foo-bar
%%   Foo, bar!
%% \stoptexdefinition
%%
%% \foo-bar

\stoptext
