Issue ID: 23847
Summary: Error with regards to lambda function is confusing
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: normal
Priority: P1
Component: dmd

void main()
{
immutable int c;
int function(int x) func;
func = x => c;
}
(13): Error: function `main.__lambda3(__T1)(x)` cannot access variable `c` in
frame of function `D main`
There are 2 problems:
1. __lambda3 is a compiler generated identifier that should not see the light
of a screen.
2. the compiler say `function` but what it outputs is actually a template
declaration.
A better error message would look like: "Error: lambda function: `x => c`
cannot access variable `c` in frame of function main.
