Not possible to redefine functions

[IlyaOrson]

julia> using Infiltrator

julia> @infiltrate
Infiltrating top-level frame:

infil> test(x) = x
test (generic function with 1 method)

infil> test(x) = x
ERROR: cannot define function test; it already has a value
Stacktrace:
 [1] top-level scope
   @ none:0

Is it possible to redefine functions inside infiltrator somehow?

[IlyaOrson]

Apparently it is also problematic to use any anonymous function after the first one:

julia> using Infiltrator

julia> @infiltrate
Infiltrating top-level frame:

infil> x -> x
#1 (generic function with 1 method)

infil> x -> x
ERROR: cannot declare #1#2 constant; it already has a value
Stacktrace:
 [1] top-level scope
   @ none:0

infil> x -> sin(x)
ERROR: cannot declare #1#2 constant; it already has a value
Stacktrace:
 [1] top-level scope
   @ none:0

Thank you for the fix. FWIW I have noticed that sometimes the error still appears but after executing it again once or twice it disappears and everything works correctly.

Any chance you can find a reproducer for this?

[IlyaOrson]

It has been tricky because every time this happens once I cannot reproduce it really.
I copy here a small example that I just stumbled upon today in case it is an useful hint for now.
I will keep an eye open for a MWE.
