\version "2.20.0"
#(regexp-substitute/global #f
   "(c|sh|w)ould of"
   "I would of done that if I could of."
   'pre 1 "ould have" 'post)

Gives:  Unbound variable: regexp-substitute/global

Also:
\version "2.20.0"
#(regexp-substitute/global #f "[ \t]+" "this   is   the test" 'pre "-" 'post)

Gives:  Unbound variable: regexp-substitute/global

What am i missing?

Thank you, ƒg
