// String escape sequences — double-quoted strings only.

// Single-quoted strings stay raw.

// --- Basic escapes ---

echo "tab:\there"

echo "newline:\nsecond line"

echo "cr:\rafter-cr"

echo "quote: \" backslash: \\ apostrophe: \'"

echo "nul byte:<\0>"

// --- Hex and unicode ---

echo "\x41\x42\x43" // "ABC"

echo "\u{1F600}" // 😀

echo "\u{41} \u{42}" // "A B"

// --- Suppressing @ interpolation with \@ ---

@name = "world"

echo "hello @name" // interpolates → "hello world"

echo "hello \@name" // literal → "hello @name"

// --- Raw strings keep backslashes ---

echo 'tab:\there' // literal backslash-t-h-e-r-e

echo 'no @interp here' // literal @interp

// --- Unknown escapes are kept as-is (forgiving) ---

echo "\q literal" // prints "\q literal"

// --- Escapes inside interpolated expressions ---

@line = "line1\nline2"

echo @line // two lines
