Well, there are macros, which do something very similar.  As far as I
know, they are the only way to achieve this kind of thing without some
Elisp.

You could do something like:

#+MACRO: => @@latex:$\rightarrow$@@

but that actually doesn't seem to work as is, I suspect because "=>" is
not an allowable macro name.  (It works fine with an alphabetic name
like "ARR".)  But even if you got it to work, you'd then have to type

Some text {{{=>}}} other text after the arrow

in your document, which sort of defeats the point of the nice, simple
"=>".  If it were me, I'd opt for the regex replacement, and avoid
typing all the braces.
 
Best,
Richard
