Semicolons

Nitrogen’s formal grammar uses semicolons to denote the end of a statement or expression. However, Nitrogen uses automatic semicolon insertion where possible. Semicolons are inserted after an identifier, literal, nil, a closing parenthesis, curly or square bracket, and after the keywords return, break, and continue. This requires the programmer to keep in mind how they’re formatting code. For example, the following if statement is invalid:

if (var == 3) // A semicolon is inserted here which will fail
{
    print("It's a 3")
} // Same here
else // And here
{
    print("No, it's not 3")
}

But the following is syntactically valid (though not recommended):

if (var == 3) { print("It's a 3") } else { print("No, it's not 3") }

The parser will catch any such errors and will warn the programmer.
