Complete ternary expression creates an Option

[versvisa]

Version: 0.5.7.9

On the REPL: (if (1 < 0) 12 else 34).to_string()

Expected result: "34"

Actual result:

KontrolSystem.TO2.Runtime.REPLException: <inline>(1, 24): Type 'Option<int>' does not have a method or field 'to_string'

This should be fixed in pre-release 0.5.8.0 (https://github.com/untoldwind/KontrolSystem2/releases/tag/v0.5.8.0).
I was already working on improvements to the REPL system. The command-line is not integrated into the console itself (not entirely finished yet).

I'm surprised that the outcome is different for REPL vs. normal code.

I just stumbled over this while debugging another issue, which turned out to be my fault.
