 ## Limitations/Bugs
 ## ================
-## Since `check` will rewrite some programs for
-## supporting checkpoints (namely assigns expressions to variables).
-## Some type conversions are not supported.
+## Since `check` will rewrite some expressions for supporting checkpoints
+## (namely assigns expressions to variables), some type conversions are not supported.
 ## For example `check 4.0 == 2 + 2` won't work. But `doAssert 4.0 == 2 + 2` works.
 ## Make sure both sides of the operator (such as `==`, `>=` and so on) have the same type.
