My 2 cents contribution:

\def\printPrime#1{#1 is prime.\crlf}

%% Why using parameter for this?
\def\arePrime[#1]{%
\bgroup
\processcommalist[#1]\printPrime
\egroup}

%% Expand the parameter before processing
\def\arePrimeN[#1]{%
\bgroup
\getparameters[Prime][p=,#1]
\expandafter\processcommalist\expandafter[\Primep]\printPrime
\egroup}

\starttext
\arePrime[2,3,5]
\arePrimeN[p={2,3,5}]
\stoptext
