To avoid confusion.
In practice we are talking about two functions where we can remove
RT errors: hb_hGet() and hb_hDel(). We do not want to touch RT errors
in direct hash access. Removing RT errors from hb_hDel() will make their
behavior similar to aDel() function which does not generate RT error
in code like aDel( {}, 2 ). With hb_hGet() it's a problem with returning
value when key does not exists because hash can hold any values.
So we can leave it as is and reduce the problem to:
hb_hDel( {=>}, "key" )
Should it generate RT error or not.
