I just ran a quick measurement on a convenient sample of 85,000 lines of
C and C++ code.  Based on this sample "**" appears on average about once
per every 200 lines of code.  This is a pretty high occurance.  For comparison
"^" [XOR] appears on average once per 3000 lines of code!  Based on this
measure I'd much rather see "^^" used for exponentiation, since the potential
for confusion would seem to be much much lower.  Too bad "^" was misused to
mean XOR in the first place or the problem would be solved!
