The main advantage of having proper functions for these code patterns is that the functions can have proper documentation.

• incrementShift s = s + bitsPerSubkey (Done in Introduce nextShift #432)
• anyMatch b1 b2 = b1 .&. b2 /= 0
• isolateLowestSetBit x = x .&. negate x (Alternative to countTrailingZeros for bitmap iteration #424)
