supported value types : string, array, slice, map supported argument types : int {{ value | lengthis 3 }} This function also supports unicode strings. Examples If input is {{ "Go" | lengthis 2 }}, the output will be true.
But,in Go, it is a map from int to DFAState. Collisions in hash values are never checked because it's a mapping of hash value to DFAState not DFAState to DFAState. So, a new state is not created. @parrtThis is a serious problem. ...
