- Types:
int, number, string, bool, void, map, and user-defined types (uppercase)
- Numeric Literals: decimal, hexadecimal (
0xFF), binary (0b1010), octal (0o77), and underscores (1_000_000)
- Strings: single and double quotes with escape sequences
- Builtins:
print, assert, sqrt, pow, len, json_encode, json_decode, has, keys, skills, skill_get, etc.
- Pyro Builtins:
pyro_exec, pyro_env, pyro_args, pyro_time, etc.
- Foreign Blocks:
>C(...), >Go(...) with special delimiter colorization
- Operators: arithmetic, bitwise, logical, null-coalesce (
??), ternary (? :), and compound assignments (+=, <<=, etc.)
