is an alias for `cl-block
' in `
Define a lexically-scoped block named NAME
may be any symbol. Code inside the BODY
forms can call `cl-return-from'
to jump prematurely out of the block. This differs from `catch' and `throw'
in two respects: First, the NAME
is an unevaluated symbol rather than a
quoted symbol or other form; and second, NAME
is lexically rather than
dynamically scoped: Only references to it within BODY
will work. These
references may appear inside macro expansions, but not inside functions
called from BODY
