Creating Internal DSLs in Kotlin
summary
Kotlin features shown as concrete tools for internal DSLs: infix functions, extension functions, and lambdas with receiver (implicit receiver) are used to drop parentheses and inject context. Examples build working mini‑DSLs: "2 days ago" / "2 days from now" date arithmetic, a meeting builder that parses "planning meeting starts at 3:15" and prints the time, and a robot script like "turns left runs fast"; each example compiles and runs in the demos.
