I too thought about using map() equivalent to comprehension and it seems to me a good reason and perhaps there are others in favor of this choice.  
In the case of the DSL “niche” of the DataFrames context, I propose the introduction of a “plus function” with the symbol “+\>” which has higher precedence than “=\>” 😁.  
We would thus have that “+\>” “wins” over “=\>” which “wins” over “-\>”  
After all “+” \> “=” \> “-”
