There's only one body indeed, but it comprises multiple forms.
The Elisp manual currently contains over 50 occurrences of body...,
including the following:
-- Macro: dolist (var list [result]) body...
-- Special Form: catch tag body...
-- Macro: ignore-errors body...
-- Macro: defun name args [doc] [declare] [interactive] body...
-- Macro: lambda args [doc] [interactive] body...
-- Macro: defsubst name args [doc] [declare] [interactive] body...
-- Macro: defmacro name args [doc] [declare] body...
-- Macro: with-eval-after-load library body...
-- Special Form: eval-when-compile body...
Whereas it only contains 7 occurrences of '&rest body':
-- Macro: pcase-defmacro name args [doc] &rest body
-- Macro: with-connection-local-variables &rest body
-- Macro: gv-define-setter name arglist &rest body
-- Macro: gv-letplace (getter setter) place &rest body
-- Macro: minibuffer-with-setup-hook function &rest body
-- Macro: with-coding-priority coding-systems &rest body...
-- Macro: with-temp-message message &rest body
[Note that with-coding-priority uses both &rest and body...]
And let-alist is the only occurrence of a body without either &rest or
an ellipsis:
-- Macro: let-alist alist body
Of course there is also the forms... style, of which there are under 20
occurrences, including:
-- Special Form: progn forms...
-- Special Form: if condition then-form else-forms...
-- Macro: when condition then-forms...
-- Macro: unless condition forms...
-- Special Form: while condition forms...
-- Special Form: let (bindings...) forms...
I don't mind which style is preferred, but let-alist should probably
pick one of the existing ones, right? Any preference?
Thanks,
