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 " |" should¹ 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.

¹) open

and if the filename ends with a '|', the filename is interpreted as a comma +nd which pipes output to us.
For three or more arguments if MODE is '|-', the filena +me is interpreted as a command to which output is to be piped +, and if MODE is '-|', the filename is interpreted as a command +which pipes output to us.
