Integrating LilyPond expressions inside Scheme functions

It is possible to use fragments of LilyPond syntax inside Scheme, by putting them between #{ and #}. In this example, three functions are defined to apply different paddings on the TextScript markups, using native LilyPond commands such as \override TextScript #'padding.

withPaddingA = #(define-music-function (padding music) (number? ly:music?)
		 #{ \override TextScript.padding = #padding
		 $music 
		 \revert TextScript.padding #})

withPaddingB = #(define-music-function (padding music) (number? ly:music?)
		 #{ \override TextScript.padding = #(* padding 2)
		 $music 
		 \revert TextScript.padding #})

withPaddingC = #(define-music-function (padding music) (number? ly:music?)
		 #{ \override TextScript.padding = #(+ 1 (* padding 2))
		    $music 
		    \revert TextScript.padding #})
