That sounds bad. I hope you'll get better!

It seems the accessibility/discoverability of string handling is 
a common complaint. People expect certain functions to be 
available for strings, like startsWith, trim/ltrim/rtrim, repeat, 
maybe even regex matching. Now, these things are all available in 
other parts of Phobos, or easily implementable using components 
from all over the standard library, but a beginner won't know 
this, and even if, it's inconvenient.

Maybe we should add the most common functions to `std.string`? 
Either as aliases or re-exports, or even (re)implement them there 
with the appropriate semantics if necessary. For example, people 
would expect a hypothetical `std.string.repeat` to be eager, 
whereas `std.range.repeat("hello").take(5)` is lazy. Some 
operations may also decay to ranges of `dchar`, but we'd want to 
preserve the string type.
