In zig you get a compile error if you exceed 1000 backwards branches (e.g. a loop or a function call). If you want to raise the quota you bump it with e.g. `@setEvalBranchQuota(2000);`. This is how we solve the halting problem :)

Anyway if you want to know why your compile time is slow in a given zig project, you can probably get pretty far by grepping for calls to that builtin.
