Issue #13125 has been updated by Robert Mosolgo.


> "reverse" of RTEST()

How about ... 

- CTEST() 
- TEST2BOOL()
- C2BOOL() 

Hope those help brainstorm a bit :)

Bug #13125: MRI has too much Qtrue : Qfalse;

```
% git grep -P 'Q(true|false|nil|undef)\s+:\s+Q(true|false|nil|undef)' | wc -l
211
```

Out of those 211 occurrences the most interesting lines include:

```
complex.c:#define f_boolcast(x) ((x) ? Qtrue : Qfalse)
math.c:#define f_boolcast(x) ((x) ? Qtrue : Qfalse)
range.c:#define RBOOL(v) ((v) ? Qtrue : Qfalse)
rational.c:#define f_boolcast(x) ((x) ? Qtrue : Qfalse)
```

I strongly believe that we need an orthodox way to do this.
