It's often useful to be able to hide a word from the global dictionary. This can be done with the lexical scope words, but here I present a different approach.
To hide a word, it is sufficient to change its name to something that will never be matched. Since strings are null terminated, just replacing the first character with a null suffices.
So all that needs to be done is to create an array of headers we want to hide, then iterate over that to smudge out the names.
