The manual [says](https://nim-lang.org/docs/manual.html#syntax-precedence):
> Whether an operator is used as a prefix operator is also affected by > preceding whitespace (this parsing change was introduced with version > 0.13.0): > > echo $foo > # is parsed as > echo($foo) Same applies here. `RIn -1` is parsed as ``RIn(-1)`. The example the manual gives here might be hard for one to generalize, but the manual does contain more clarities for popular pitfalls, the other biggest one I can think of being [limitations of the method call syntax](https://nim-lang.org/docs/manual.html#templates-limitations-of-the-method-call-syntax).
