MPSCM[1] has a parallel let form.

Eli, can you point me to language in the R5RS or R6RS that forbids  
interleaving the evaluation of the initializers in a standard let  
form? The R6RS just says, "The <init>s are evaluated in the current  
environment (in some unspecified order)". I think that allows the  
evaluation of the initializers to be interleaved or parallelized.
