Checking if a variable is exported

[Martijn Dekker <martijn@xxxxxxxx>]

Hi all,

Does zsh have a straightforward way for a script to check if a variable
is exported? The closest-to-straightforward way I know of is to parse
the output of 'typeset -p varname', which is hairy because the output
might include various options to the command.

Thanks,
