Despite the fact that many native functions are overloaded, no. The last function definition simply overwrites the prior ones.

q)f: {[x]}
q)f: {[x; y]}
q)f
{[x; y]}
q)

We are not aware of an available q-to-native-code compiler.

If your goal is to prevent clients from being able to read your code, see this related faq.

The q language has only 3 non-atomic data structures:

  • lists
  • dictionaries
  • tables

However, q does use other structures internally (e.g., hash tables) to enhance the performance of operations on the above language-level structures.
