Take a look at the rdmd documentation:

https://dlang.org/rdmd.html

There you'll see this:

rdmd [dmd and rdmd options] progfile[.d] [program arguments]

That means any arguments you pass on the command line after the 
source file name will be passed to your program. Compiler options 
need to go before the source file name.

rdmd -L-lreadline mysource.d
