Implement regular expressions, replace, and iterable maps

[kaidesu]

Regular Expressions

pattern := "i need (.*)"

pattern.matches("i need coffee") // true
pattern.findAll("i need coffee") // [i need coffee, coffee]

Replace

"hello world_".replace("_", "!") // hello world!

Iterable Maps

reflections := {
    "am": "are",
    "was": "were",
    "i": "you"
}

for (index, value in reflections) {
    print(index)
    print(value)
}
