Hi, dear list. Is there a proper "ConTeXt way" to do the following?

\integerdef\lmao=0
\starttext
Sum: \in[trick] % 10 from the result below

+1\advance\lmao\plusone

+2\advance\lmao\plustwo

+3\advance\lmao\plusthree

+4\advance\lmao\plusfour

\normalexpanded{\reference[trick]{\the\lmao}} % 10 printed above
\stoptext

I want the result of a sum (either via Lua or TeX) to be printed before
summands in text, but without the mess of reference options such as
interaction, etc. Thank you in advance and sorry for any inconvenience.

Regards,

Jairo
