cl--loop-letcl--loop-let is a compiled Lisp function in `
cl-macs.el'. (cl--loop-let SPECS BODY PAR) Build an expression equivalent to (let SPECS BODY). SPECS can include bindings using `cl-loop's destructuring (not to be confused with the patterns of `cl-destructuring-bind'). If PAR is nil, do the bindings step by step, like `let*'. If BODY is `setq', then use SPECS for assignments rather than for bindings.
