There's probably a fancier answer to that, but you can just shell out to

This may end up being just a slower, different, equally hard-to-parse way
of accomplishing what you were already doing via reg query, but powershell

Currently having a mental block about this here. Why does this code:

I have a bunch (~1000) of x,y,z and a corresponding value, V. One unique V
for each x,y,z. I want to interpolate and extrapolate wildly (so I really
don't care about how accurate or correct it is). The x,y,z I have are not
regularly spaced or anything. They're scattered across some range (they
My guess is that this has something to do with currently lacking facilities
for type inference on global variables. If you wrap your indirect approach
in a function, you get the predictable behavior:
julia function f()
xvals = [ d for d in 1.0:10.0 ]
xxvals = [ (d,d) for d
Often a package uses a library in the system, or more specifically, the
package is an interface to a library. The library should be installed as

Is your concern that some other package might also export non-mutating

that type inference on global variables is difficult because there aren't
clearly defined boundaries without which the variable cannot be

Here you have the same problem though. If I also defined assoc and deassoc
people could not include the two libraries without conflict. I'm also of the
mind that the verbs should be consistent with the more common mutable

Now that you mention it, I think the only reason I made it a subtype of

performance. I will re-examine that decision now, I think. Thanks for your
