Iterating through a set of polar coordinates
This plots five vertices of a pentagon:
begin{tikzpicture}
defVerts{
{0:1},
{72:1},
{144:1},
{216:1},
288:1
}
foreach Vert [count=i] in Verts {
% Draw vertex
node at (Vert) {textbullet};
}
end{tikzpicture}
However, this will not and report the error No shape named {288,1} is known.
begin{tikzpicture}
defVerts{
{0:1},
{72:1},
{144:1},
{216:1},
{288:1}
}
foreach Vert [count=i] in Verts {
% Draw vertex
node at (Vert) {textbullet};
}
end{tikzpicture}
Why does the last element of the array need to not be enclosed in braces?

The curly braces are not the issue. The issue is an excess space that the parser sees. You can fix this by adding a %.
documentclass[tikz,border=3.14mm]{standalone}
begin{document}
begin{tikzpicture}
defVerts{
{0:1},
{72:1},
{144:1},
{216:1},
{288:1}%
}
foreach Vert [count=i] in Verts {
% Draw vertex
node at (Vert) {textbullet};
}
end{tikzpicture}
end{document}
Alternatively you could use
defVerts{
{0:1},
{72:1},
{144:1},
{216:1},
{288:1}}
Again, the excess space is gone. (The other coordinates have a comma right after the closing }, so there is no such space.)
