Hey Scott,
Just bumped across an old IJulia Notebook my 9-year old and I did last
year. He was getting '24' problems (use +,-,*,/ with 4 numbers to make 24)
and got one he swore couldn't be solved. We put together a little
brute-force solver to test that out -- he was right.
The problem appears to be in the recently introduced check to isfinite
(line 143), which turns an array of things into an array of bool.

I'll concede that if you know the function name at runtime, Mauro's
solution may be a little cleaner, especially if it will be called a lot.
There are plenty of examples in Base of @eval being used to define
functions, such as lines 11-18

Following up on an earlier discussion that I started in this newsgroup, I
have written a small package that provides a routine to modify a field of
an immutable object in the case that the object is inside a container.
Please refer to:
https://github.com/StephenVavasis/Modifyfield.jl
I have now implemented a solution that follows Mauro's basic outline. The
difference is that the heavy lifting in my code is done at compile-time
instead of run-time so that modifyField! will have good performance even in
an inner loop. Please see my announcement soon to be posted on

I tried a similar build yesterday, but ran out of disk space over night on

It could be worth it to try configure options similar to what is mentioned

It would seem that they must be forcing on codegen with -mattrs=+vfp, but I
didn't think you could do that at compile time.

Since you don't provide msk nor display the value of rect, it's hard to say.
BTW, in julia you can say
