+;; HACK `geiser' has poor autoload etiquette. It calls
+;;      `geiser-activate-implementation' and `geiser-implementation-extension'
+;;      in their autoloads files. Sure, these functions are autoloaded, but this
+;;      needlessly (and unavoidably) pulls in the `geiser-impl' package (et co)
+;;      when geiser-X's autoloads are read (i.e. at startup).
+;;
+;;      I rectify this by inlining calls to these two functions (and the
+;;      `geiser-impl--add-to-alist' sub-call in
+;;      `geiser-implementation-extension'), and autoloading the two variables
+;;      they operate on. I do this from our autoloads file (which is
+;;      byte-compiled and read at startup before package autoloads).
+;; TODO At some point, PR this behavior upstream (but not verbatim!)
