Consider this code:
function give_funs()
funs = []
for i in 1:5
function newfun()
i
end
funs = [funs, newfun]
end
funs
end
The intention is to create 5 functions and store them in a list called
"funs".
All the functions take no argument, and when the ith function is called, it
returns i.
However, when run...
funs1 = give_funs()
funs1[1]() # this should give 1, but instead it gives 5
funs1[2]() # this should give 2, but instead it gives 5 as well
This is problem goes away if I stop naming the function as "newfun" but
instead use ananymous functions like so:
funs = [funs, () -> i]
however in real code I would like to give it a name so to be more clear
what the function is suppose to compute
It seems that these functions are bound by their function names, and since
they're all named "newfun", the compiler over-write the old ones defined
earlier.
How should this be resolved?
