Function patch_seq_env_get_int 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_env_get_int(
    env_data: *const Value,
    env_len: usize,
    index: i32,
) -> i64

Get an Int value from the closure environment

This is a type-specific helper that avoids passing large Value enums through LLVM IR. Returns primitive i64 instead of Value to avoid FFI issues with by-value enum passing.

Safety

• env_data must be a valid pointer to an array of Values
• env_len must match the actual array length
• index must be in bounds [0, env_len)
• The value at index must be Value::Int

FFI Notes

This function is ONLY called from LLVM-generated code, not from external C code. The signature is safe for LLVM IR but would be undefined behavior if called from C with incorrect assumptions about type layout.
