I have a table member of an object declared as such
entries: Table[string, string]
Run
And I was returning it with this
proc getAll*(this: JotzCollection): Table[string, string] =
return this.entries
Run
When I try to get its length
assert(collection.getAll().len == 2)
Run
I get a spew of errors

This seems to be telling me there is no len function for tables? I can call len
just fine on the table from within the proc. What am I missing? Thanks!
