Variable name with special characters
Declaring a variable in GHCi with $ . is allowed, but they are not referable. I suppose that the parser should impose more restrictions at this.
*Main> let a$1 = 10
*Main> a$1
<interactive>:20:1: Not in scope: ‘a’
Prelude> let a.1 = 10
Prelude> a.1
<interactive>:9:1: Not in scope: ‘a’
Prelude> let a%1 = 1
Prelude> a%1
1
Prelude> let a^1 = 1
Prelude> a^1
1
Prelude> a^1 + 1
2
