I have actually found a work around as well, which was to wrap

it's not a "workaround", it's almost exactly what i did in my

just not that hairy.
you can't get address of anything in compile time, 'cause there
is no
such address. but you can do it in runtime, of course. that's
what you
doing: postponing "&" to runtime.
as far as I could google, no one has attempted this yet.
no one published it yet, not "no one attempted". i desperately
need
runtime reflection for my (still private) component builder
project, so
i'm slowly writing that mechanics. and my "command console"
using
similar technique to allow user inspect variables and classes,
and call
function/methods in runtime.
I do something possibly similar for generating console help text
using runtime reflection. It could have used compile-time
reflection, but it gets annoying to use.
Using
https://shardsoft.com/stash/projects/SHARD/repos/dap/browse/source/dap/Standalone.d
(with
https://shardsoft.com/stash/projects/SHARD/repos/shardtools/browse/source/ShardTools/CommandLine.d
and
https://shardsoft.com/stash/projects/SHARD/repos/shardtools/browse/source/ShardTools/Reflection.d?until=45ded3019f3f05d7b68e5746d34da1de7433ccf6),
it generates something like:
D Asset Pipeline
Converts assets into an intermediate post-processed format more
efficiently loaded at runtime.
Commands:
[-h|--help]: Displays the help string.
[-a|--add]: Adds the given raw asset to the asset store
using the default processor and default settings.
[-r|--remove]: Removes the asset with the specified
qualified name from the asset store.
[-l|--list]: Lists all assets currently stored.
[-b|--build]: Builds all dirty assets using current
settings.
[-i|--inspect]: Shows all properties of the given asset.
[-m|--modify]: Modifies a property of a processor on an
asset, or the processor used to build the asset.
Options:
[--input-folder]: The folder that assets should be read
from and settings stored in. Default: Content\Input
[--output-folder]: The folder that generated assets
should be saved to. Default: Content\Output
[--log-level]: The minimum severity for a message to be
logged. Default: info
The command lines then invoke methods registered through runtime
reflection, which allow the user to change individual properties
on the set processor using --modify, again using runtime
reflection to find the setting that the user wants and converting
their input to the appropriate type.
