Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I edited the description to clarify the two scenarios you pointed out. thx
There should be specification on the precedence of variable lookup. If
valuesandglobalhas the same key, which one is used first? What happens ifvaluescontains keys such as4, should{{4}}use the key invaluesor the literal?Also, what happens if lookup fails?
It need more random tests.
