Constant variables can now be declared inside functions. They follow the same scoping rules as normal variables.
Variable declarations can now have a constant expression to denote it's size in memory.
Static assertions at the top level.
New sizeof keyword for use with automatic and buffer variables. It also can be used inside constant expressions.
Improved error message for duplicate indentifiers.
Constant folding is back in code generation. Was present in the V stas compiler, missing till now.
The noeval function attribute to disable the constant folding behavior.
The layout in memory of auto variables has been reversed to be in line with what would be assumed.
String length is excluded from the push_str instruction, with it being pushed separately.
NASM bootstrap files have been included in the bootstrap/ folder.
--trace-calls compiler switch. The compiled executable will have function calls traced at runtime.
Inline functions can now use the ret keyword.
Test runner written in V. The accompanying file, make_bootstrap.sh, calls test runner.
