You're making it too complicated. This is the reason the cascade exists. Simply provide your element selectors and class your color:
h1 {
color: #000;
}
.a-theme-color {
color: #333;
}
Then apply it to the elements in the HTML, overriding when you need to use your theme colors.

My answer will relate to Java, as that is what I know. Interfaces describe behavior, and not implementation. Additionally, static fields are tied to the classes, and not instances. If you declared the following:

$path = trim($base . '/' . $uf);
That could be causing it. I'm assuming $base is some sort of root folder you are searching, so if $uf is something like '', '.', or '../' that could return true. We would have to see what values you are using in your foreach to know anything further. |

The inconsistency is due to use. `vector` is a sequence having an ordering over the elements.

In C, `goto` only works within the scope of the current function, which tends to localise any potential bugs. `setjmp` and `longjmp` are far more dangerous, being non-local, complicated and implementation-dependent. In practice however, they're too obscure and uncommon to cause many problems.

Typically, integer values are signed, unless you explicitly need an unsigned value. It's just the way they are used. I may not agree with that choice, but that's just the way it is.

Unsigned int's aren't CLS compliant and would therefore restrict usage of the property to those languages that do implement a UInt. For example VB.NET has no notion of UInt16/UInt32/UInt64
