Works! I placed it in a freshly made juliarc.jl. Thanks!

I'm on an isexpr() evangelism mission. Also going to use if statements for
additional exposition.
using Base.Meta
macro allconst(args...)
exp = Expr(:block)
Wah! Right, I can't even read that. I'll try and learn more about the
metaprogramming. Thanks!

Macros are useful for this sort of thing.
```
macro allconst(args...)
exp = Expr(:block)
args[1].head == :block && for a in args[1].args
a.head == :(=) && push!(exp.args, Expr(:const, Base.esc(a) ))
end
exp
end
@allconst begin
I often define a bunch of constants at the beginning of a program. Wouldn't
it be nice if we could start an environment of constants to avoid writing
`const` before every one of the rows at the beginning of a program?
Kind of like:
```Julia
begin const
a = 1
b = 2
c = "neverChange"
end
```
