MODULES 179 Default top-level definitions and bare modules Modules automatically contain using Core, using Base, and definitions of the eval and include non-constant global variables in Julia, especially in tight loops. Since you can write close-to-metal code in Julia (unlike Python), the effect of globals can be drastic (see Performance Tips). • In
