scheme@(guile-user)> (define str2 "hello")
scheme@(guile-user)> (string-set! str2 4 #\a)
ice-9/boot-9.scm:1669:16: In procedure raise-exception:
string is read-only: "hello"

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> ,q
scheme@(guile-user)> (string? str2)

is it a bug in Guile ? :-O

i can only find reference to deprecated read-only string in old doc:
