A simple fold roles up any term, replacing #\n\ - # it with ... until it is expanded again. #\n\n\ - let fold = in\n\n\ - # 2. A semantic fold covers a term with a property: #\n\ - # Click to toggle inferred & synthesized types #\n\n\ - let folds: = in\n\n\ - # Projectors on literal data are called livelits. #\n\ - # Three base types literals use inline views: #\n\n\ - let guard: Bool = in\n\ - let phase: Int = in\n\ - let float: Float = in\n\n\ - # Inline error decorations (same as for tokens) #\n\n\ - let (a:Int, f: Float) = , in\n\n\ - # The String base type get a multiline view: #\n\n\ - let _ = in\n\ - let __ = in\n\ - let ___ = in\n\ - let ____ = in\n\ - let _____ = in\n\ - let ______ = in\n\n\ - # Multiline error decorations #\n\n\ - let box: Int = in\n\n\ - # ERRATA: #\n\ - # The bottom toggle can also be used to remove #\n\ - # projectors. Currently only bidelmited terms can #\n\ - # projected, so some may have to be parenthesized. #\n\ - # Projectors are persistent across sessions, but #\n\ - # currently are lost on cut/copy.
