I am writing lambda function. I need filter data at first step
and than do dome operation on them (for start simply print on the
screen. I wrote next code:
MySQLTablesRange.filter!(a=>a[0].coerce!string.canFind("_")).each!(a =>
to!int(a[0].coerce!string.split("_")[1]).writeln);
But it's seem that each do not handle any data. I tested if data
is corectly filtered and next code successfully print it's output.
auto t =
MySQLTablesRange.array.filter!(a=>a[0].coerce!string.canFind("_"));
t.each!(a=>a[0].coerce!string.writeln);
But what is wrong with first code?
