From the Crema wiki that I just glanced at, it is indeed not possible to write infinite loops:

"The only type of loop supported by Crema is the foreach loop. This loop is used to sequentially iterate over each element of a list. Crema specifically does not support other common loops (such as while or for loops) so that Crema programs are forced to operate in sub-Turing Complete space. In other words, foreach loops always have a defined upper bound on the number of iterations possible during the loop's execution. This makes it impossible to write a loop that could execute for an arbitrary length of time."
