```Another case of "does this make sense?"

Let's experiment with Limit....

In[36]:= 1 + 1/(x+a)

1
Out[36]= 1 + -
x

In[37]:= Limit[%,x->Infinity]

Out[37]= 1            ********* ho hum **********

In[38]:= 1 + 1/(1+a)

1
Out[38]= 1 + -----
1 + x

In[39]:= Limit[%,x->Infinity]

Out[39]= 1            ************** yawn **********

In[42]:= 1 + 1/( x+a)

1
Out[42]= 1 + -----
a + x

In[43]:= Limit[%,x->Infinity]

Out[43]= 1       ****************  zzzzzzz  ***********

In[45]:= 1 + 1/(b x)

1
Out[45]= 1 + -------
a + b x

In[46]:= Limit[%,x->Infinity]

1
Out[46]= 1 + ----------------   ************** what???? *************
a + b (Infinity)

*** so, maybe the multiplication's **
*** got mma upset **

In[47]:= 1 + 1/(b x)

1
Out[47]= 1 + ---
b x

In[48]:= Limit[%,x->Infinity]

Out[48]= 1                  *****  nope, just another one of those days ****

Is there a consistantcy problem here, or is this just
a new form of computer generated cream of wheat
(with the lumps like mom used to make.. )
