So do use it.  It is possible and supported, just not by a simple
setq.

Here's the defcustom of that option from glasses.el:

  (defcustom glasses-separator "_"
    "String to be displayed as a visual separator in identifiers.
  It is used both for adding missing separators and for replacing separators
  defined by `glasses-original-separator'.  If you don't want to add missing
  separators, set `glasses-separator' to an empty string.  If you don't want to
  replace existent separators, set `glasses-original-separator' to an empty
  string."
    :type 'string
    :set 'glasses-custom-set
    :initialize 'custom-initialize-default)

What does the :set attribute tell you?
