"""
String(g::Base.Generator)

Create a new `String` from a `Generator` by joining all elements.
Each element is converted to a string via `print`, and the results are concatenated.

# Examples
```jldoctest
julia> String(x for x in ['a', 'b', 'c'])
"abc"

julia> String(Iterators.map(identity, "hello"))
"hello"
```
