If a function of zero arguments, then its result is used.
If a list of functions, then all functions must return nil to
activate yas for this buffer.
`yas-minor-mode-on' is usually called by `yas-global-mode' so
this effectively lets you define exceptions to the \"global\"

In Emacsen <= 23, this variable is buffer-local. Because
`yas-minor-mode-on' is called by `yas-global-mode' after
executing the buffer's major mode hook, setting this variable
there is an effective way to define exceptions to the \"global\"
activation behaviour.
In Emacsen > 23, only the global value is used. To define
per-mode exceptions to the \"global\" activation behaviour, call
`yas-minor-mode' with a negative argument directily in the major
mode's hook.")
