Warning: ‘loop’ is an obsolete alias (as of 27.1); use ‘cl-loop’ instead. [9 times]

I get following warning when executing eval-buffer on calfw-blocks.el:
src/calfw-blocks/calfw-blocks.el: Warning: ‘loop’ is an obsolete alias (as of 27.1); use ‘cl-loop’ instead. [9 times]
In attempt to silence warning I created following patch:
