Definitely. You see, the problem is that programming languages are designed on US-QWERTY keyboard, therefore the choice of syntactic special characters is made according to the characters easily available on a US-QWERTY keyboard. Indeed, you will never see a programming language where §, ¡ or ¿, are meaningful characters. (Actually, and this is a confirmation, there is one language where you had characters such as ∂§¶⨍, it was MPW scripts, (Macintosh Programmer's Workshop scripting language), because those characters were easily available (using the option modifier) on a Macintosh keyboard). Therefore, until you invent a Spanish programming language using characters easily accessible on a Spanish keyboard layout, it will be easier as a programmer, to use a US-QWERTY keyboard layout.
