dear,
it seem now we can not use this:
 ";;;;;;blah".stripLeft(";");
 Error: template std.string.stripl(String) cannot deduce template
function from argument types !()(string,string)


they are another way ?

In Python str.lstrip accepts an optional argument:

>>> ";;;;;;blah".lstrip(";")
'blah'


But I think with the current Phobos you need to use something like this:

import std.stdio, std.string;
void main() {
    string s = ";;;;;;blah";
    munch(s, ";");
    writeln(s);
}

None of the strip or split functions in Phobos deal with anything other than whitespace. splitter is more general, but there is no stripper (which would arguably be a horrible name for a function anyway). However, that's essentially what find does, albeit with the predicate effectively being reversed. e.g.

find!"a != ';'"(";;;;;blah");
