I suppose that word-at-point is a simple extension of the thing-at-point
mechanism, that uses forward-word instead of the syntax table.

One difference I could make out is that word-at-point respects
find-word-boundary-function-table (as it is implemented via
forward-word). This means that when something like subword-mode is
active and the buffer contains

       someCam|lCaseWord

where | is the point, (word-at-point) returns "Camel" while
(current-word) gives me "someCamelCaseWord".
