I'm sure different people will react differently, but my intuition is quite
the opposite: I would probably call the inline assignment to the property
an "initial value", not a "default value", and I would intuitively compare
it to assigning it in the constructor. I would also understand the intent
of "write once" to be "once initialized, can't be overwritten", so would
personally have no expectation that I could initialize a variable in both
the property definition and the constructor.
