[stringtemplate-interest] howto set separator in parallel list iteration

[Jens Boeykens]

Looks like the parallel iteration doesn't work correctly either. I miscopied
my input...

input:            INT -> test(a={$int}) | CHAR -> test(b={$CHAR})
output:          INT -> test (a = {$int}) CHAR -> test (a = {$int})

So it is correct for the first list [INT, CHAR], but it doesn't iterate over
the second list [-> test(a={$int}), -> test(b={$CHAR})]
The "-> test(b={$CHAR})" doesn't appear in the output. Instead the first
element is displayed twice

What I want to generate is (same as input):
Expected output:  INT -> test(a={$int}) | CHAR -> test(b={$CHAR})

Greetings
