It's the other way round. Regarding typeset and declare, the man page 
says: " When used in a function, makes  each name local, as with the 
local command. " So within a function, typeset, declare, and local are 
synonyms. Using 'local' outside a function is an error, so IMHO this 
command is completely redundant. It _would_ make some sense, however, if 
its counterpart 'global' existed, as it could help clarify the intended 
usage of the variable.
