I think that must be, a best codify the definition of functions
f(x,y):= 4*y^4-5*x²*y²+x^4 => f:=(x,y)->4*y^4-5*x²*y²+x^4
best
f(x,y):= 4*y^4-5*x²*y²+x^4 => f(x,y) -> 4*y^4-5*x²*y²+x^4
f(x,y):= 4*y^4-5*x²*y²+x^4 => f(x,y) -> 4*y^4-5*x²*y²+x^4
apply( ans, {1}) =>
apply( f(x,y) -> 4*y^4-5*x²*y²+x^4, {1}) => [4*y^4-5*y²+1]
associate list of lists in parallel to each variable of the function
apply( f(x,y)->4*y^4-5*x²*y²+x^4,{{1,3},{2,4}}) => { [45] [385] }

* requires a new command ENTRY, purpose: to call a History entry quickly without having to go to the x line
