Partial function application: Difference between revisions

=={{header|Lambdatalk}}==

Lambdatalk functions are curried, therefore, partial function application is trivial. Not giving a multi-argument function all of its arguments will simply return a function that takes the remaining arguments.

<lang Scheme>

{def fs {lambda {:f} map :f}}

{def f1 {lambda {:x} {* :x 2}}}

{def f2 {lambda {:x} {pow :x 2}}}

{def fsf1 {fs f1}}

{def fsf2 {fs f2}}

{{fsf1} 0 1 2 3}

{{fsf2} 0 1 2 3}

{{fsf1} 2 4 6 8}

{{fsf2} 2 4 6 8}

Output:

0 2 4 6

0 1 4 9

4 8 12 16

4 16 36 64

</lang>
