Description

I have the following construct:

$[env:MQTT_WRITE_HOST;default='$[prop:MQTT_WRITE_HOST;default=some.host]']

The Goal is, env -> prop -> default

The result unfortunately is not as expected. if I have no default for the props statement, the fallback works and it tries to resolve the property if the env is not set. If I have the second default for the case that nothing is set, the env immediately defaults to "some.host]".

The Quotes for the default make no difference in this case, even if I only quote the value of the last default. My current workaround is $[env:MQTT_WRITE_HOST;default=]$[prop:MQTT_WRITE_HOST;default=some.host]

Additionally a convinient version like propEnv and envProp would be nice to cover suche a case in on statement.
