std.typecons.scoped works per se (I'm adding unittests as we 
speak) but using my current dmd, this:

     // confirm scoped allocation is @nogc
     void scopedRNG(T)(T seed) @nogc
     {
         auto gen = scoped!UniformRNG(seed);
     }

     scopedRNG(unpredictableSeed);

... fails to compile with the error,

     Error: @nogc function 
'hap.random.generator.__unittestL91_27.scopedRNG!uint.scopedRNG' 
cannot call non- at nogc function 
'std.typecons.scoped!(LinearCongruentialEngine!(uint, 16807u, 0u, 
2147483647u)).scoped!(uint).scoped'

... even if the constructor of the RNG in question is marked 
@nogc together with all that it calls.

Is this possibly an issue with 'scoped'?  Was it only quite 
recently patched to support @nogc?  I'll update my installed 
compiler if so.
