Bug?: Concatenating strings

[corwin42]

This gives a syntax error:

str = "This " & 2 + 2 & " is a test"

but this

str = "This " & (2 + 2) & " is a test"

works fine.

Bug or feature?

Expected behaviour when you consider operator precedence.

Is there somewhere a list of all operators with its precedence? I haven't found one.
