# What this teaches:
#   • Minimal multi-feature happy path across 函数, 常量, 如果, and 显示.
#   • Related keywords: 函数, 常量, 如果, 显示
#
# Common mistakes:
#   • Writing code outside `入口` that produces side effects — top-level code runs at module load; prefer `入口` for program entry.

# 函数 name(params) → type { … }
# 常量 _ n ← expr
# 如果 <cond> { … }
# 显示 template with § interpolation

# GRAMMAR:
#   funcDecl   :← '函数' ident '(' params ')' ('→' type)? block
#   condStmt   :← '如果' expr block
#   outputStmt :← '显示' expr
#
# EXPECTED OUTPUT:
#   minimum-smoke.expected — par 42 when n is even.

fn par(int n) → bool {
    return n % 2 ≡ 0
}

main {
    const int n ← 42
    if par(n) {
        print "par §"(n)
    }
}

Expected output:

par 42
