A single period (`.`) + indicates that the item currently sitting atop the context stack should be + used; otherwise, name resolution is as follows: + 1) Split the name on periods; the first part is the name to resolve, any + remaining parts should be retained. + 2) Walk the context stack from top to bottom, finding the first context + that is a) a hash containing the name as a key OR b) an object responding + to a method with the given name. + 3) If the context is a hash, the data is the value associated with the + name. + 4) If the context is an object, the data is the value returned by the + method with the given name. + 5) If any name parts were retained in step 1, each should be resolved + against a context stack containing only the result from the former + resolution. If any part fails resolution, the result should be considered + falsey, and should interpolate as the empty string. + Data should be coerced into a string (and escaped, if appropriate) before + interpolation. + + The Interpolation tags MUST NOT be treated as standalone. +tests: + -
