I tried the supplied scripts, but didn't get the results you describe.
I get:
[martyn:0]$ PATH=$PATH:/tmp /tmp/test1.pl
In BLOCK1, $ENV{WANGO} = [undef]
In BLOCK2, $ENV{WANGO} = [FOTANGO]
In BLOCK3, $ENV{WANGO} = [undef]

Please retry them in a separate session; I have to imagine that you have
"WANGO" set in your environment, or similar.
