With the #1=f[#2]& notation, where does the pure function start? A typical use of the shorthand may be: myfunc = #1<#2& Clearly in this case you want myfunc to be set to this pure function. The same applies to #1=f[#2]&, you are trying to set the "symbol" #1 to f[#2]&. This is not allowed. To clear up the ambiguity, use brackets: (#1 = f[#2])& Hope that helps.
