#= A comment that consists of several lines.
The following code itself is rather useless unless you want
to test how Julia code is displayed by the jlcode package. =#

# This line will be my reference line, which will contain exactly 80 characters.

# This line is a comment containing operators like &, -, $ and %
# A comment with the German word "Übergrößengeschäft" (store for oversizes)
# This line contains some special unicode characters: €, α, γ, w², Δₓ, Ϋ, x̃, ℯ
# A comment with some numbers: 424, 1.23, 0.2E-5, -9.9e+9, 1_001
# Mathematical characters that are Julia functions:
# |, |>, ~, ×, ÷, ∈, ∉, ∋, ∌, ∘, √, ∛, ∩, ∪,
# ≈, ≉, ≠, ≡, ≢, ≤, ≥, ⊆, ⊇, ⊈, ⊉, ⊊, ⊋, ⊻, ⋅
# Other mathematical symbols: ∇, ⊗, ⊕, ‖, …, ⋯, ⋮, ⋱, ⋰

# defining a useless testfunction
