`clear' feature request

[Joao Cardoso]

Hi,

Well, Santa Claus has already gone, but I still keep asking gifts :-)

Should a plain `clear' clear global variables? Some of my scripts keep
internal state information (and share information) in global variables.
>From time to time I issue a `clear', and all them are (obviously)
cleared. Perhaps an option, `clear -g [pattern]' to explicitly clear
global variables only, could be added?

Thanks,
Joao
