as a side note... you can use value? to test for a value within a context at
that moment (or otherwise if its been defined globally).
I use it sometimes to delay the refresh of things which can run in an gui or
not, or which have a chance of being run before the gui is opened...
ex:
unless value? 'gui [
show gui
]
