// Phase 200-D: Minimal capture test (Pattern 2)
// This test verifies that captured variables work in JoinIR Pattern 2
// without using substring or other unsupported methods.
//
// Key points:
// - base/offset are captured (function-scoped constants)
// - No substring/indexOf in body-local init (Phase 193 limitation)
// - Simple accumulation using captured value
// - Break condition: i == 100 (never true, just to trigger Pattern 2)
static box Main {
main() {
local base = 10 // Captured var (used in multiplication)
local offset = 5 // Captured var (used in addition)
local i = 0
local v = 0
local n = 3 // Loop 3 times
// Pattern 2: loop with break (break never fires)
loop(i < n) {
// Simple break condition that never fires
if i == 100 {
break
}
// Use captured variable in accumulation
// v = v + base
// For i=0: v = 0 + 10 = 10
// For i=1: v = 10 + 10 = 20
// For i=2: v = 20 + 10 = 30
v = v + base
i = i + 1
}
print(v) // Expected: 30
}
