I accept your reasons for doing so. 
But actually this behaviour makes the "==" comparision to a "maybe".
"Maybe they are equal." Documentation of this working will be helping not 
much. The users of PHP have to understand the working of "==" at the lowest 

I suggest, that you check your convert to a number. If the result is MAXINT, 
MININT or NaN, it would be better not converting the operands and making a 
string comparision.  
In this case you havn't to make an extra documentation on this behaviour and 
this operation will work like users expect.
