I don't see what it would break, besides the pre-processor usage.
Exactly: "‘import’ ignores preprocessor state within the source file". But what I don't understand is that on a few slides later it says: "What Does import Import?" And: "Functions, variables, types, templates, macros, etc." Note it says "macros".
Modules mean that the compilers just need to read a symbol table or an AST from an external file.
That's basically how it works: 1. Find a module map for the named module 2. Spawn a separate instance of the compiler: 2a. Parse the headers in the module map 2b. Write the module file 3. Load the module file at the ‘import’ declaration 4. Cache module file for later re-use I think this is only to be compatible with pre-existing headers. -- /Jacob Carlborg
