The full module may look like:
#%Module
if {[module-info mode load]} {
switch -- [module-info shelltype] {
sh {puts stdout "FOO='my\nmulti\nline\nvalue'; export FOO;"}
}
} elseif {[module-info mode unload]} {
unsetenv --unset-on-unload FOO
}
Regards,
Xavier

This shows me that the module load must outputting a string to bash that is only setting the first line of the file to the variable FOO, then the subsequent file lines are getting dropped right to bash to evaluate.
