Description
!screenshot-1.png!In the following example, the definition of myMethod is not correctly updated:
------------------------------
def myMethod() = "first definition"
val tmp = myMethod(); val out = tmp
println(out) // prints "first definition"
def myMethod() = "second definition" // override above myMethod
val tmp = myMethod(); val out = tmp
println(out) // should be "second definition" but is "first definition"
------------------------------
I'm using semicolon to force two statements to be compiled at the same time. It's also possible to reproduce the behavior using :paste
So if I-redefine myMethod, the implementation seems not to be updated in this case. I figured out that the second-last statement (val out = tmp) causes this behavior, if this is moved in a separate block, the code works just fine.
EDIT:
The same behavior can be seen when declaring variables :
------------------------------
val a = 1
val b = a; val c = b;
println(b) // prints "1"
val a = 2 // override a
val b = a; val c = b;
println(b) // prints "1" instead of "2"
------------------------------
Interestingly, if the second-last line "val b = a; val c = b;" is executed twice, then I get the expected result
