Hello,
according to my understanding of the "put" method for ranges, which is part of the output-range interface, the following should work :

private string[] m_arrHalloStrings = ["Hallo", "Du", "Da", "wie", "?"]; m_arrHalloStrings.put("Hallo");

it compiles but does not execute:
the compiler gives the message

core.exception.AssertError@std.array(256): Assertion failure

Best regards, Oliver

I found out that an "appender" or operator ~= will work,
but still do not understand why put makes the program terminate.

I can't reproduce this.  It works for me.  I'm guessing you have an older version of DMD, since with 2.031, std.array.put is no longer on line 256.  Try updating.
