as tables like those in setuphead({somehead}, {somesettings}) are actual Lua tables and follow Lua, not TeX, rules But there are lua apis that support delayed TeX like `context.chapter(context.delayed'text')`. Whether or not the function is stored in a table should be theoretically irrelevant. I guess there should be a switch somewhere that let the command recognized delayed function.

On the Lua side, you'll have to pass strings so your example works, as tables like those in setuphead({somehead}, {somesettings}) are actual Lua tables and follow Lua, not TeX, rules (see e.g. Lua reference in https://www.lua.org/manual/5.4/ or, better, CLD manual in http://www.pragma-ade.nl/general/manuals/cld-mkiv.pdf):
\starttext
\startluacode
--First example
for m = 1, 3 do
context.setuphead({'chapter'}, {before='hello'})
context.startchapter({title="I'm a chapter!"})
for i = 1, 3 do
context.input("knuth")
end
context.stopchapter()
end
--Second example
--We'll pass some strings to TeX
local nice = "ConTeXt is love, ConTeXt is life"
local somehead = 'chapter'
local sometext = 'vallejo-trilce-es'
context.setuphead({somehead}, {before=nice})
context.startchapter({title=somehead})
context.input(sometext)
context.stopchapter()
\stopluacode
\stoptext
I hope examples help.
Regards,
Jairo :)

Dear List,
I'm trying to mirror the context command `\setuphead[chapter][before=hello]` into lua with delayed typesetting of 'hello', but `\ctxlua{context.setuphead({'chapter'}, {before=context.delayed'hello'})}` does not have any effect. Could anyone help me on this? Thanks!
Best, Sylvain
