Insert paired delimiters

With C-u resp active region with wrap symbols

Examples, cursor after pipe-symbol:

(defun foo1 |       ==> (defun foo1 () 

With active region until end of region

|interactive        ==> (interactive)

keep padding:

| foo               ==> ( foo ) 

Works also with reachable unary delimiters:

|interactive      M-x simple-paren-colon RET  ==> :interactive:

Mathematicians resp. logicians might use

M-x simple-paren-ogham-feather-mark RET ==> ᚛᚜

or

M-x simple-paren-mathematical-double-angle-bracket RET ==> ⟪⟫

M-x simple-paren- TAB should display what's implemented.

Easy to extend:

If a command inserting mathematical white square brackets wouldn't exist:

(defun simple-paren-mathematical-white-square-bracket (arg)
  (interactive "*P")
  (simple-paren--intern ?⟦  ?⟧ arg))

The mode provides keys like that:

[(super \()] 'simple-paren-parentize

[(super \/)] 'simple-paren-slash)

[(super \<)] 'simple-paren-lesser-than)

Conceived for a deliberately non-electric use
