+      //
+      // When dealing with a tree, which contain free values, toolboxes extract those and wrap the entire tree in a Function
+      // having parameters defined for every free values in the tree. For example, evaluating
+      //
+      //   Ident(setTypeSignature(newFreeTerm("x", 2), <Int>))

+      // Note that free values get transformed into, effectively, by-name parameters. This is done to make sure
+      // that evaluation order is kept intact. And indeed, we cannot just evaluate all free values at once in order
+      // to obtain arguments for wrapper.wrapper, because if some of the free values end up being unused during evaluation,
+      // we might end up doing unnecessary calculations.
+      //
+      // So far, so good - we didn't need any flags at all. However, if the code being reified contains path-dependent types,
+      // we're in trouble, because valid code like `free.T` ends up being transformed into `free.apply().T`, which won't compile.
+      //
+      // To overcome this glitch, we note whether a given free term is stable or not (because vars can also end up being free terms).
+      // Then, if a free term is stable, we tell the compiler to treat `free.apply()` specially and assume that it's stable.
