+/**
+ * Strips characters that are not significant to the validity or execution
+ * of a GraphQL document:
+ *   - UnicodeBOM
+ *   - WhiteSpace
+ *   - LineTerminator
+ *   - Comment
+ *   - Comma
+ *   - BlockString indentation
+ *
+ * Note: It is required to have a delimiter character between neighboring
+ * non-punctuator tokens and this function always uses single space as delimiter.
+ *
+ * It is guaranteed that both input and output documents if parsed would result
+ * in the exact same AST except for nodes location.
+ *
+ * Warning: It is guaranteed that this function will always produce stable results.
+ * However, it's not guaranteed that it will stay the same between different
+ * releases due to bugfixes or changes in the GraphQL specification.
+ *
+ * Query example:
+ *
+ * ```graphql
+ * query SomeQuery($foo: String!, $bar: String) {
+ *   someField(foo: $foo, bar: $bar) {
+ *     a
+ *     b {
+ *       c
+ *       d
+ *     }
+ *   }
+ * }
+ * ```
+ *
+ * Becomes:
+ *
+ * ```graphql
+ * query SomeQuery($foo:String!$bar:String){someField(foo:$foo bar:$bar){a b{c d}}}
+ * ```
+ *
+ * SDL example:
+ *
+ * ```graphql
+ * """
+ * Type description
+ * """
+ * type Foo {
+ *   """
+ *   Field description
+ *   """
+ *   bar: String
+ * }
+ * ```
+ *
+ * Becomes:
+ *
+ * ```graphql
+ * """Type description""" type Foo{"""Field description""" bar:String}
+ * ```
