builder error:
==================
C error found. It should never happen, when compiling pure V code.
This is a V compiler bug, please report it using `v bug file.v`,
or goto https://github.com/vlang/v/issues/new/choose .
You can also use #help on Discord: https://discord.gg/vlang .
If const num_elements = 10 is in the main module then the compilation succeeds.
Reproduction Steps
See above.
Expected Behavior
Either the fact that it is invalid to use non-module-local const variables as array dimensions should be documented as such with a suitably information compiler error, or this should be supported and documented.
Current Behavior
See above.
