Emacs provides the binding conditionals if-let, if-let*,
when-let, when-let*, and-let* and while-let.
This package implements the missing and-let and while-let*,
and the original cond-let, cond-let*, when$, and$ and and>.
This package additionally provides more consistent and improved implementations of the binding conditionals already provided by Emacs. Merely loading this library does not shadow the built-in implementations; this can optionally be done in the context of an individual library, as described below.
cond-let and cond-let* are provided exactly under these names.
The names of all other macros implemented by this package begin
with cond-let--, the package’s prefix for private symbol.
Users of this package are not expected to use these unwieldy names. Instead one should use Emacs’ shorthand feature to use all or some of these macros by their conceptual names.
Please see the library header for usage information and the docstrings for information about the individual macros. See also https://github.com/tarsius/cond-let/wiki.
