The moment a language is the output of a natural language compiler, the language itself is kind of irrelevant.
Change the skills, ask the agent to do exactly the same in something else.
I am slowly focusing on agent orchestration tools, which make the actual programming language as relevant as doing SOA with BPEL.
The language may be irrelevant, but the hard guarantees it offers are not. Agents are still very stochastic, they need something deterministic constraining their output.
