Fwiw this "quirk" was well known when we designed the syntax. For me it's a 
feature, either write `x + y` or `x+y`; `x +y` is ugly and inconsistent.

This is so you can do things like 


echo -3


Run

which parses as `echo(-3)` instead of `echo - 3`. Same goes for


echo [1, 2, 3]
echo @[1, 2, 3]
# parsed as
echo([1, 2, 3])
echo(@[1, 2, 3])
# iinstead of
echo[1, 2, 3]
echo @ [1, 2, 3]


Run

Nim requires you to use consistent spacing around binary expressions. So you 
can do no spaces on both sides, `a+b`, one space, `a + b`, two spaces `a + b` 
but you can't do one space on the left and no spaces on the right, `a +b`. As 
people said, this is a quirk of the command syntax `someProc arg1, arg2`.

It's an inconsistent spacing problem and a quirk of the command syntax.

a + b is ok. a +b is not. a +b is equivalent to a(+(b))

Thx you. I find interesting (and maybe a bit confusing) that

> echo(x+y+z+a+b+c)

with no spaces is ok

Interesting that


var x, y, z = 3


Run

is allowed. Have not really guessed that a 3 vars would get initial value 3.

For your problem:

echo(x + y + z + a + b +c) is evaluated as echo(x + y + z + a + b(+c))

Because Nim can accept arguments without () as we use generally for echo.

Hy there, i'm a newbie, sorry if my question is silly.

This code is ok:

> var x, y, z = 3
> 
> let a, b, c = 4
> 
> echo(x + y + z + a + b + c)

but this is not:

> var x, y, z = 3
> 
> let a, b, c = 4
> 
> echo(x + y + z + a + b +c)

missing a blank in "+c". Compiler says

> Error: attempting to call routine: 'b'
> found 'b' of kind 'let'

Why? Thx.

Is there a syntax sheet of the differences between python 2 and 3 to fix a compiling problem?

I'm honestly finding it hard to learn when I'm working and one piece of code 
works with one software but not another. Like I needed to make a coin flip 
histogram. Issue is that the guy who I found the code for and modified wrote it 
in python 2.x (I heavily modified it because while I am learning I do have HW 
due. I added to it to make it a histogram and fixed it a bit)

I went on Visual Studio got all the libraries for it just to run the code. 
Issue was that VSC ran it hella slow (like were supposed to run it 30 series 
with each series 100times). Matlab handled that ok from what I've heard but my 
code just running it 1000times (not the 3000 times the HW ask for) kinda slows 
the computer. So I thought why not post it into another IDE but the online ones 
(since it's a relatively small amount of code they should be ok) don't seem to 
work since I keep getting syntax errors. I posted the code. Run it 1000 times.
