string as a lookup variable?

[StephenOTT]

Currently when doing lookups in aggregations, there is the .variableDefinition() and .variable

The variable definition supports a custom name argument (especially useful when doing lookups on nested props). But it seems you cannot set a custom name on the variable. And I cannot seem to create a variable from a String. Which requires manual creation such as "\$\$myVar"

Thoughts on allowing "myVar".variable which will prefix the $$ just as it does for a KProperty path ?

thanks

Nice idea. I'm going to add it.
