Found a workaround: The idea is to use \csname …\endcsname with two delimiters
not likely to be used in math mode, below chosen to ‘…’.
But then there seems to be a bug in the LuaTex \letcharcode command: There must
be a character between “$” and the first occurring \activecatcode letter.
Possibly this also causes a bug in \startformula, as discussed before.
it's not a bug .. tex looks ahead for a second $ and in the process
expands the next token which happens to be a letter at that point so it
gets injected as letter (it's the way tex works)
\appendtoks
\catcode`𝐝\lettercatcode
\catcode`𝐢\lettercatcode
\catcode`𝐦\lettercatcode
\to \everymathematics
\definemathcommand[𝐝𝐢𝐦][nolop]{\mfunction{𝐦𝐢𝐝}}
\starttext
Note that $ \𝐝𝐢𝐦 𝑉 = 𝖫$, although $\dim 𝑉 = 4$.
And a bug: $\𝐝𝐢𝐦 𝑉$.
\stoptext
fwiw, the current beta makes math characters also letters now
