_ArraySearch return 0 (number vs string)

[JKFN]

#Include <Array.au3>
Dim $array[1]
$array[0]=0
$output=_ArraySearch($array,"string")

$output is not -1, but 0

I may be mis-interpreting something here but it is my understanding that:
[from Helpfile, Datatypes]

If a string is used as a number, an implicit call to Number() function is done.
So if it doesn't contain a valid number, it will be assumed to equal 0.
For example,

10 * "fgh" equals the number 0.

So I'm not completely surprised that the comparison made (0 = "string") is interpreted as (0 = Number("string")) which is (0 = 0) and thus succeeds at index 0 of the array given in exemple.

Disclaimer: of course it can be objected that comparing oranges with keyboards is by itself a bad idea. OTOH the variant nature merely invites such operations.

The equality test is essentially:

0 = Number("string")

The statement Number("string") returns 0 which compares true against 0 which means the search was successful and the index was found.

This is not a bug.
