+### Control Structures
+
+#### `if <cond> <lambda>`
+Execute the given lambda if `cond` is truthy. Cond may be a lambda, in which case it is executed.
+A value is truthy UNLESS it is the literal empty string (`''`) or the integer `0`.
+Example: `foo` -> `if (contains foo) (suffix bar)` -> `foobar`
+
+
 ### Misc

 #### `lipsum <num> <word|line|para>`
