Thanks. I tried that just now: 
    
    
    ms:nim jim$ nim c -d:danger --gc:arc str1
    Hint: 11937 LOC; 0.390 sec; 12.988MiB peakmem; Dangerous Release build; 
proj: /Users/jim/nim/str1; out: /Users\
    /jim/nim/str1 [SuccessX]
    
    ms:nim jim$ /usr/bin/time -l ./str1
    100000001
            0.90 real         0.73 user         0.15 sys

Does this need 1.3x?
