Usage of split with semicolon

When I am chasing my work with Tcl code, surprised by the below code's output.

#!/usr/bin/tclsh
puts [split {a:b:c:d} :]
puts [split {a;b;c;d} ;]
puts [split {a-b-c-d} -]
puts [split {a b c d} ]; # 'space' will be taken as split-char here.

Output:

a b c d
{a;b;c;d;}
a b c d
a b c d

As you can see, {a;b;c;d;} is a list with one element.

With semi-colon as the separator character, split is returning the whole input as one single element-ed list instead of providing each word as each element for that list.

A semicolon is also an optional statement end indicator.

Try:

 puts [split {a;b;c;d} {;}]

I'm wondering why it didn't give a syntax error though.
