That was my idea.

Actually you could call a wrapper-shell-script which sources and calls a second perl-script.

The perl-script use Data::Dumper to serialize %ENV and prints the string to STDOUT.

opening the shell script with " |" should be sufficent to grab the dump.

the second perl-script might look overhead but it's cleaner and you don't need to worry about k/ba/c-sh compatibilities and about JSON.
