- Regarding "Vesterman's paradox":

- What if the description is rephrased as follows:
-
- the smallest positive integer that cannot be specified uniquely
- in plain English using no more than 150 ASCII characters
-
- Now the only mapping of interest is the one that maps strings of
- characters to unambiguously specified integers via the semantics of
- English. (If the string does not describe an integer, or if two
- educated speakers of English might disagree on the integer specified,
- then the string is not in the function's domain.)
-
- *Now* how is the paradox resolved? (Hint: quite easily, in my
- opinion.)
