# Imported constants in fixed-array lengths A fixed-array length referring to an imported constant respects its import alias. For `import sizes as fx`, `[fx.max_items]int` uses `sizes.max_items`, even when another module is named `fx` and imported under a different alias. When the same alias has different meanings in different source files, constant resolution leaves the length unresolved rather than falling back to a real module with the alias name. Compile-time fixed-array size quantifiers support `$d()`; other forms, including `$env()`, remain errors even when the environment value is empty or contains an integer.
