   ### Search before asking
   
   - [X] I had searched in the 
[issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and 
found no similar feature requirement.
   
   
   ### Description
   
   Currently var pool only support '${setValue(key=value)}', which has a 
limitation that value cannot reference other variables.
   
   For example, 
   
   ```shell
   d=$(date "+%F %H-%M-%S")
   echo '${setValue(day=${d})}'
   ```
   Since single quotes won't interpolate anything, we cannot use ${d} in 
${setValue}, so I think we can support #{setValue(key=value)} to avoid this.
   
   like follow:
   
   ```shell
   d=$(date "+%F %H-%M-%S")
   echo "#{setValue(day=${d})}"
   ```
