## Global namespace
When using namespaces, you may find that internal functions are hidden by functions you wrote. To fix this,
refer to the global function by using a backslash before the function name.

### String types
Strings are a series of characters, which should sound fairly simple. That said, there are a few different types
of strings and they offer slightly different syntax, with slightly different behaviors.

Single quotes are used to denote a "literal string". Literal strings do not attempt to parse special characters

If using single quotes, you could enter a variable name into a string like so: `'some $thing'`, and you would
see the exact output of `some $thing`. If using double quotes, that would try to evaluate the `$thing` variable
name and show errors if no variable was found.

Double quotes are the Swiss Army Knife of strings. They will not only parse variables as mentioned above, but all sorts

When using interpolation, it is often the case that the variable will be touching another character.
This will result in some confusion as to what is the name of the variable, and what is a literal character.

To fix this problem, wrap the variable within a pair of curly brackets.

### Which is quicker?
There is a myth floating around that single quote strings are fractionally quicker than double quote strings. This
is fundamentally not true.

If you are defining a single string and not trying to concatenate values or anything complicated, then either a single or
double quoted string will be entirely identical. Neither are quicker.

If you are concatenating multiple strings of any type, or interpolate values into a double quoted string, then the results can
vary. If you are working with a small number of values, concatenation is minutely faster. With a lot of values, interpolating
is minutely faster.

Regardless of what you are doing with strings, none of the types will ever have any noticable impact on your application.
Trying to rewrite code to use one or the other is always an exercise in futility, so avoid this micro-optimization unless you really
understand the meaning and impact of the differences.

## Variable declarations
At times, coders attempt to make their code "cleaner" by declaring predefined variables with a different name. What
this does in reality is to double the memory consumption of said script. For the example below, let us say
an example string of text contains 1MB worth of data, by copying the variable you've increased the scripts execution to
2MB.
